Is There Air Temperature On The Moon
1. Describe and give examples of the various ways that heat can be transported in the atmosphere. There are a variety of ways that heat can be
transported in the atmosphere. The first method is conduction. According to Ahrens (2015) conduction is referred to when heat shift from one
molecule to another (p. 33). A reoccurred example of conduction we see every day is when we cook. You put a pan on the stove and turn on the stove
top. The heat from the burner transfers to the cold pan to heat the pan. The next method is convection. Ahrens (2015) stated, "the transfer of heat by
the mass movement of a fluid (such as water and air) is called convection" (p. 33). An example of convection is the operation of a convection oven.

According to Ahrens (2015), the earth's atmosphere contains nitrogen (N2) and oxygen (O2), with small amounts of water vapor (H2O) and
carbon dioxide (CВ¬2) (p. 4). Scientists believe the process for formation of today's earth's atmosphere started billions of years ago. Ahrens (2015)
stated the earth's first atmosphere was comprised of hydrogen and helium as well as methane and ammonia but is believed to have escaped into
space due to the heat of the earth (p. 5). The assumption here is that a second atmosphere was created due to the excessive heat from volcanoes and
steam vents comprised of mainly water vapor and carbon dioxide with trace amounts of nitrogen (Ahrens, 2015, p. 5). As the earth started to form its
rivers, lakes, and oceans the water began to absorb mass amounts of the carbon dioxide converting the atmosphere into a nitrogen and oxygen rich
atmosphere (Ahrens, 2015, p. 5).
4. Many people will blow on a bowl of hot soup to try to cool it. In your view, what are the two most important heat transport processes cooling the
soup? In my view, the two most important heat transport processes cooling the soup are conduction and convection. For conduction, heat will
always rise to seek colder a cold region. This is why you see steam or vapor coming off of a bowl of soup. For convection, we are applying the same
elements of conduction, however we are adding current or wind to displace the heat which will rise

Indirect Clorimetry And Temperature
1. A calorimeter is an instrument that we can use for direct and indirect calorimetry, which can give us volume measurements of CO2 and O2 that our
lungs exhale and inhale during a certain time frame. Direct calorimetry can be defined as a method where the body gauges the quantity of energy it has
produced and its body rate through direct measurement of the heat that is produced in the body. Indirect calorimetry can be defined as a method of
measuring the body's respiratory gases that will give us an estimate of the body energy expenditure.

Temperature Of Water Investigation
The purpose of the experiment was to investigate the effect of the temperature of the water on the reaction of the tablet. There was a difference
between the tablet in the cold water and the tablet in warm water. The tablet in cold water took 32.17 seconds to completely dissolve, and it took
the tablet in warm water 26.67 seconds to completely dissolve. The hypothesis is that if one puts a tablet in cold water and one in warm water, then
the water in cold water will take a longer time to dissolve and the tablet in the warm water will dissolve faster was supported. I got this result because
the added energy in the hot water causes water molecules to move faster which make the tablet dissolve faster, and the tablet in colder water took a
longer time because the cold water is condensed. This experiment relied on the temperature of the water how cold and how hot the water is. Perhaps

There was a significant difference between the crushed tablet and the whole tablet. The crushed tablet tokk 20.5 second to completely reacted and
the whole talet took 27.23 seconds to completely reacted. The hypothesis is that if one takes a tablet and splits it in a half and takes one side and
crushes it up into many tiny pieces, and leaves the other hole and put them both in water then the crushed tablet will take a shorter time to reaction
and the whole tablet will take awhile to reaction because the crushed one has more surface area which will make it reaction faster. This hypothesis
was supported. This experiment relied on the tablet of how much do we put in the water. Perhaps this experiment could be improved by complete

Fermentation : The Effect Of Temperature Essay
Fermentation: The Effect of Temperature
Introduction
Fermentation is a metabolic pathway that allows a cell to perform cellular tasks by shifting the energy in the glucose bonds to the bonds in ATP in the
presence of less oxygen. Fermentation occurs to allow the process of Glycolysis to continue to produce ATP for the cell. In the process of fermentation,
NADH is oxidized. Pyruvate directly gains the electrons from NADH, instead of the electrons going to the electron transport chain. To better
understand fermentation, one could compare cellular respiration with fermentation. Cellular respiration is a longer process that includes Glycolysis,
pyruvate processing, the citric acid cycle, and the Electron transport chain. However, if oxygen levels needed are not present, Glycolysis produces
pyruvate which yields diverse products in fermentation. Variables can effect fermentation, such astemperature. Temperature can cause kinetic energy in
reactions. If the temperature was high, reactions in fermentation can speed up because molecules have excited electrons. However if the temperature is
at an extreme, molecules such as proteins can denature. Brownian movement can be exemplified in a solution subjected to kinetic energy because
movement of molecules are irregular, disorganized, and agitated. The process of fermentation is significant due to its importance and impact on living
organisms. Observing the reactants and products of fermentation can lead to a better understanding

The Effect Of Temperature On Our Cognition
Introduction
When a person describes someone, as being "warm" one understands it as a person who is friendly and not as someone who is physically warm.
Using temperature as a way to describe a person has been understood as a metaphor, however studies have revealed that there is a connection between
the association of warmth and feelings of social belonging (Ijzerman et al., 2012).
The belief that our physical world has an influence on our cognition is called the embodiment theory (Chen, Poon & Dewell, 2014). In this theory it is
believed that our surroundings shape of psychological feelings (Chen et al., 2014). Hence, why we use temperature as a way to expressing feelings. The
following studies have conducted different types of ... Show more content on Helpwriting.net ...
Participants were divided into two different groups and would have two different food–drink types. They were then led to a computer where they would
play a ball–tossing exercise game. The participants believed that they were playing with two other players online, however the game was
programmed with no real players. One group was only passed the ball twice in 30 throws while the other group received the ball frequently. Finally,
the participants were handed a survey that measured which foods they desired more and it was found that the socially excluded group desired warm
food (Zhong & Leonardelli, 2008).
The following study read these results and hypothesized that perhaps a person feeling a room to be colder because their body temperature actually
becomes colder. This study followed the exact same procedure as the ball–tossing game Zhong and Leonardelli (2008) presented, however the
participants temperature would be recorded this time. For this experiment 41 participants were recruited from VU University. The participants were
also divided into two groups where one would be thrown the ball only twice and the other an evenly distributed amount of times. A device that was
located on their index finger measured all participants' temperature continuously, which along the way revealed that the participants body temperature
went down in the exclusion group (Ijzerman et al., 2012).
From Ijzerman et al.(2012) observations they hypothesized that if warmth was introduced

The Effect Of Temperature On The Air Temperature
Results
Subterranean Temperature Neither the sheltered microclimates occupied by the terrestrial isopods or the ambient environment reached a lethal
temperature in the Clark Fork riparian zone during the October to November 2015 study period, however, subterranean lows varied significantly from
ambient temperatures. During the period of stable daily weather fluctuations of mid to late October subterranean daily mean temperatures varied
insignificantly from ambient temperatures (p = 0.75). Further deviation in the mean occurred with an increase in the intensity of temperature swings late
in the observation period. Subterranean lows varied significantly by approximately 3В°C from ambient lows during the mid to late October uniform
temperature period (p = 0.02). The sheltered temperature remained on average 2.5В°C warmer than the ambient air temperature later in the season.
Ambient lows exceeded the subterranean low on two abnormally warm days in late October (Figure 2). Overall, the subterranean microclimate
remained significantly warmer than the ambient temperature (p = 0.0001). The sheltered temperatures were largely warmer between 11/4 and 11/10
showing an increase in the rate of temperature decrease relative to the ambient temperatures. However, the rate of temperature decline across the
sample period did not vary significantly between the two climates (p = 0.37).

Temperature Enzyme Activity
The entirety of this experiment was to conclude if temperature had an effect on enzyme activity. The experiment tested the perimeters of enzyme
activity and to see whether or not the temperature had an effect on the amount of substrate produced. Enzymes are especially well known for being
catalyst within a reaction (Royal Society of Chemistry). A catalyst is, in this case anenzyme, which speeds up a reaction by lowering the activation
energy required to start the reaction (Royal Society of Chemistry). Previous research has shown that while the temperature rises reacting molecules have
more kinetic energy. The more kinetic energy each molecule has, the greater the chance of reaching its point of highest catalytic activity (Royal Society

Temperature Increase In The Rainforest Ecosystem
1. During a summer day the air temperature goes through the most fluctuations. It is much easier for the ambient air temperature to increase and
decrease rapidly. It takes much longer for the much denser ground to both heat up and cool down. During the day the sun's radiation heats up the air in
the atmosphere. This happens for many hours and causes large increases in temperature. The air temperature increases as this occurs, whereas the
ground takes much longer. Additionally when the sun sets the temperature begins to drop. The air temperature drops rapidly, but the ground
temperature does not. This is due to the insulating properties that the ground possesses. Therefore it can keep a certain temperature for longer and is
more resistant to ... Show more content on Helpwriting.net ...
Theses similar patterns do not mirror the patterns observed in the summer data. The primary reason for this is due to the fact that the reduced amount
of sun from a lower aspect and less time in the sky means that both ecosystems don't have time to be affected. Both soil temperatures sit around the
same average since there is no real exposure to sun and both are insulated. The natural density of dirt and other contributions to the soil insulate it from
temperature changes. The air temperature in both ecosystems fluctuates with the same patterns and are similar. The approaching winter means that
naturally temperatures will go down and the lack of sun is a large factor which causes a normalizing effect on the ecosystems, it brings them down to

Can Temperature Ever Be Lower Than Dewpoint Temperature?...
1.Can temperature ever be lower than dewpoint temperature? why or why not?
Air Temperature is a measurement of the average kinetic energy of the particles in the air, or how hot or cold the air is. Dewpoint is the temperature
at which water vapor begins to condense out of the air and form dew, and a measure of how much moisture is in the air. If thetemperature reaches the
dewpoint then dew will begin to form. If the temperature is at the dewpoint and the temperature falls, the dewpoint must fall as well.

It can be artificially attained by increasing the kinetic energy of some solutions to allow more solute to dissolve into the solvent; then if a disturbance
is created (either by a seed crystal, or an impurity in the solution) the excess solute will fall out of solution. A similar effect can be seen by carefully
cooling distilled water, such as in a water bottle, down past the freezing point, carefully removing it from the freezer, and then tapping the container to
cause the whole thing to freeze at once.
Cloud seeding was an attempt to control the amount precipitation that would form (or fall out of solution) in the atmosphere by releasing condensation
nuclei in hopes of forcing more water molecules to condense on them in large enough numbers to create

Homeostasis: A Change Of Body Temperature
The body must maintain a constant state of equality called homeostasis so that our body will operate at its max potential. The definition for
homeostasis is "The tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback control, so as to stabilize
health and functioning, regardless of the outside changing conditions." (Biology–Online) So basically an organism tries to no matter its external
conditions maintain the optimal internal conditions so that its internals don't take damage from the temperature and will remain at the normal and
expected operating temperature.To do this the animal must consume energy from inside its body so that it can perform the act of maintaining
homeostasis. This energy most often comes from ... Show more content on Helpwriting.net ...
For instance, in the case temperature and homeostasis if a human's body can't actively calculate and compensate for exterior temperatures then things
like overheating or even hypothermia can occur. If exterior temperatures are lower than the required internal temperature then over time a person's
internal temperature will fall leading to hypothermia and death, but homeostasis is supposed to prevent that by using energy to maintain the correct
body temperature. If there is even a one degree change in celsius is can lead to harm for the body and usually signifies that there is something wrong not
to mention it shows just how sensitive the body and brain are to temperature changes. When there are such temperature extremes and your body has to
consume energy to control and maintain homeostasis one of the first things to be affected is your brain. The brain is one of the most important if not
the most important organ in your

Optimum Temperature Of Amylase
This experiment was needed to determine the optimal temperature at which the enzyme amylase best functions. Since an increase in temperature
speeds up the movement in molecules, the substrate is supposed to come in contact with the active site of the enzyme more quickly and frequently
until the heat becomes an obstacle by denaturing the structure of these enzymes and thus changing its function.
There were a total of four different temperatures at which amylase activity was observed (Table 1). In order to ensure that temperature was the only
manipulated variable, four test tubes were prepared with the same contents. Each tube contained about 2mL of the 1% starch solution, 4mL of
deionized water, 1mL of a 6.8 pH buffer. After 10 minutes of... Show more content on Helpwriting.net ...
It was predicted that as temperature increases, the chemical reaction would accelerate mainly because the increased temperature would speed up the
motion of molecules. "Microorganisms are efficient degraders of starch, chitin, and the polysaccharides in plant cell walls" (Warren, 183). For a
variety of biological purposes, plants break down long polysaccharide (starch) molecules into disaccharide (maltose) molecules and monosaccharide
(glucose) molecules. There is no reason to assume that amylase is the only enzyme responsible for the hydrolysis of starch (Paleg, 904). As the results
show, the reaction that consumes starch and produces maltose would eventually go to completion; however, with the addition of the enzyme amylase,
the reaction should significantly speed up. It was also determined via this experiment that the addition of amylase is not the only variable that
influenced the speed of this reaction; temperature also played a huge role. The evidence gathered in the experiment supported the hypothesis and
matched the prediction: there was a great increase in amylase activity in higher temperature experiments up until the enzymes begin to denature. There
were two ways to gather data that would prove the change in the reaction rate in presence of the amylase enzyme: the appearance of maltose or the
disappearance of starch. The second test was used for this specific

Effect Of Temperature On Hypothermia
1.)The mid–latitude summer, mid–latitude winter, and high latitude data sets show evidence of some mixing. This was determined by observing how
some deeper depths have a warmer temperature than depths that are not as deep. For example, on the high latitude temperature graph, the temperature
is 0В°C at a depth of 250 m. However, at deeper depths the temperature is warmer; one can assume that mixing took place.
2.)The mid–latitude winter water temperature and high latitude water temperature are both very low. The water temperatures in these two latitudes
range from 0В°C–10.2В°C, which could potentially cause hypothermia. To prevent hypothermia, a dry suit would need to be worn. Dry suits are more
suited for colder water since the wearer does not

property of the heat, (solid, liquid or vapor) of the substance during pressure, temperature and common desire composition is an important tool to
remember before figuring up its heat. Heat capacity could be determined by the capacity of the temperature of an object multiplied by the mass as well
as the chemical composition, temperature, and pressure of a substance (Science.com)

The results increase steadily between 0В°C and 45В°C. There is a steep increase between 45В°C and 65В°C. This is the point when the proteins in the
cell membranes are denatured causing gaps to form in the membrane, thus allowing more red pigment from the beetroot to diffuse into the distilled
water.
An increase in temperature increases the kinetic energy of betalain molecules thus increasing rate of diffusion of the red pigment from the cytoplasm
into the distilled water. The denatured proteins and an increase in the fluidity of the phospholipid causes the substance contained in the membrane to
leak out.
There is a small increase in the spectrophotometer reading between the temperatures 0C–23C. This is because the membrane structure becomes more
rigid and less red pigments leak out of the membrane.
Validity and Reliability

The experiment is repeated twice and an average is obtained. This ensures the consistency of the measurement as the reading is triplicated, thus
reducing anomalies. It can be seen that the reading obtained were around the same value. This proves that the results are reliable.
The results obtained support the hypothesis at the beginning of the experiment. Apart from that, the experiment is conducted according to the

This means that the solid pdB and the liquid pdB phase changed at 330 to 420 seconds because during a phase change, the temperature of the substance
always remains constant, thus why melting point and freezing point is the same temperature. Although temperature remains constant in a phase
change, it does not necessarily indicate one; the water day #1 curve had the temperature (x) remained constant the whole experiment, but there was no
phase change when we observed it in the lab. The graph makes us able to estimate the time when the pdB and the water reach temperature equilibrium,
which is when two different temperature substances touch each other and the hotter one (heat source) releases its heat into the cooler one (heat sink)
until the temperatures become the same (the total heat released from from heat source should equal the total heat gained by the heat sink). When the
temperature of the two day #1 curves or the two day #2 curves intersect is when they have reached temperature equilibrium; their temperatures will be

Temperature, Temperature And Gas Solubility
Temperature
Temperature is a measurement of the average kinetic energy (or speed) of atoms or molecules (Khan Academy, 2017). The most typical units of
temperature include degrees Celsius (oC), its American equivalent Fahrenheit (F) or Kelvin (K).
At standard temperature, 0oC corresponds to 273 K. However, 0K is commonly referred to as the 'absolute zero degree' where all molecular motion
would cease.
Temperature and gas solubility:
Generally, increasing temperature would cause a comparable rise in the solubility of liquid and solid solutes in liquid solvents.
A specific example includes the crystallisation of a concentrated mannitol solution at low temperatures and the redissolving of those solid crystals as
upon heating. However, ... Show more content on Helpwriting.net ...
The particles in liquids, on the other hand, although still close within the proximity of one another, are in random arrangements, having slightly more
space to move. As the particles are still held close, liquids also exhibit high densities. Water, however, is a prominent exception, being different as it
is denser as a liquid than a solid. Upon freezing, the water particles separate slightly, forming crystal lattices with space between each particle that
allow icebergs and ice cubes to stay afloat the water (BBC, 2017).
Water, nevertheless, is much denser than air as gas particles have considerable space between one and another. Water molecules, therefore, exert greater
pressure on a diver's body as he descend into the ocean than air particles would on a pilot ascending into the sky. This serves to justify why the change
in pressure is much greater for a given depth in water than for the same rise in air.
Volume
Volume can be defined as the quantity of three–dimensional space occupied by a liquid, solid or gas and is one of the most commonly used
measurements worldwide. Several of the most typical unites of volume include litres, millilitres, cubic metres, cubic centimetres and gallons
(Helmenstine, 2017). For instance, a 10–metre high rectangular tank with a base that is 4 metres in length and 6 metres in width would be able to hold
10 metres x 4 metres x 6 metres = 240 cubic

Period 3
Heat Fracture on Rocks
Background
Heat fracture is when an increase in volume is observed, due to an increase in temperature. Simply meaning that while a material is being heated, the
rise in temperature causes it to take up more space. Heat fracture doesn't only deal with high temperatures, it also deals with the effects of cooling on
a material. If cooling occurs then the opposite of expansion occurs as well, the material will begin to shrink or decrease in size. Continuous heating
and cooling will eventually lead to stress and that makes the material break or fracture. When the material going through this type of weathering is

It was believed that if the amount of time that the rock went through heating and cooling increased, then the weight of the rock would decrease
because while the rock goes through more heating and cooling eventually it will fracture causing the weight to decrease. This is called heat fracture.
The data gathered did prove the hypothesis to be correct. For the longer trials with more minutes, the rock's weight did decrease more rather than the
shorter amount of trials. For example, the one minute trial barely had a 0.6g difference proving our hypothesis correct, while the 15 minute trial had a
significant change in the rock's weight due to the longer time experiment. The graph seemed to gradually increase according to the longer trials. The
only outlier was the last trial because it had such a small change compared to the other trials, although all trials did support the original

Grow Temperature Research Paper
Discussion
This study depicted that common wombat burrows provide a constant temperature 1–2m from the entrance within four different habitats – open field,
forested, short ground cover and sandy bank – during both summer and autumn. However, noticeable differences in the temperatures between the
seasons were observed. Although, this was expected as the insulating properties of the soil stop daily, but not seasonal, fluctuations intemperature from
a depth of approximately 0.30cm (Reichman & Smith 1990), with the main factors that did influence burrow temperatures being time of day, elevation
during summer and aspect during autumn. There are few studies in the literature that display the influences of elevation and aspect on burrow
temperatures so these may present novel findings that might impact burrow location or use. The general outcome that burrow temperatures remain
constant while temperatures outside the burrow fluctuate, however, is supported in many studies of different species. Shimmin et al ... Show more

These stable temperatures within the burrow coincide with many previous studies conducted on other burrowing animals, with all studies agreeing that
the temperatures are constant daily but have a gradual seasonal change. This presents strong evidence that burrows maintain a consistent microhabitat
that is effective in providing shelter from weather extremes, thereby allowing burrows to be regarded as an appropriate mechanism of thermal tolerance.
The influence temperature has on wombat behaviour cannot be fully addressed due to the declining wombat population at the study site, however, it
may be attributed to the small ambient temperature ranges that were experienced not having a significant impact on wombat presence in this

Chickpeas Temperature Experiment
According to Figure 1, the production of carbon dioxide changed based on the temperature the chickpeas were placed in. It seemed that the chickpeas
placed into the ice bucket at 5В°C produced the most carbon dioxide; however, this is not the case since the figure is only showing measuring the
amount of ppm's recorded by the carbon dioxide sensor. To get an accurate determination iftemperature affected cellular respiration of chickpeas,
finding the slopes of the lines was necessary which was done in Table 1. This is done by using the mathematical formula m=(y2–y1)/(x2–x1) with the
"y" being the y–coordinate and "x" being the x–coordinate. To be consistent the coordinate points at the 10 second and 240 second mark were used to
find the slope ... Show more content on Helpwriting.net ...
The chickpeas in the hottest temperature tested produced the most amount of carbon dioxide meaning that the cellular respiration rate of the chickpeas
was increased. The coldest temperature tested also produced the least amount of carbon dioxide meaning cellular respiration decreased in those
chickpeas. For the most part the experiment ran more smoothly than expected. A few time during testing the test chamber was knock over but these
accident had a minimal effect on the final outcome. There were sudden jumps when testing the runs in Figure 1, but the jumps were never major
enough to cause a retrial. These jumps can be attributed to the fact that the carbon dioxide production was taken every 10 seconds in the 240 second
experiment so anything outside disturbance during that time was reflected in the data. Overall the data completely supports the hypothesis. The 42В°C
run produced the highest slope, the 5В°C run produced the lowest slope, and the room temperature (22В°) run was in between the two other slopes.
The 5В°C run did have the most amount of ppm's recorded, but this means nothing in the long run since the slope was still the lowest meaning it
produced the least amount of carbon dioxide over the 4 minutes. The results obtained corresponded with other students in the class who also tested the
relationship between cellular respiration and temperature as well as the studies discussed in the introduction

Automatic Temperature Control Fan
Abstract:
The automatic temperature control system is a very essential feature of a factory or an industry. In most of the case the temperature plays a vital role in
the process of manufacturing or the process carried in that factory or industry.
The most common and simplest way of controlling temperature is by using a fan which is automatically connected to a network such as it is switched on
when the temperature of the surroundings increases.
The change in temperature of the surroundings can be sensed with the help of thermistor or a sensistor. These electronic components sense the
temperature of the surroundings. When there is a change in the temperatue tempetature then these electronic components start to conduct the electric ...

From the above discussion it is concluded that for the having low output from the timer 555, the voltage on the threshold input must exceed the control
voltage or + 2/3 VCC. They also turn the discharge transistor on. To force the output from the timer high, the voltage on the trigger input must drop
below +1/3 VCC. This also turns the discharge transistor off.
A voltage may be applied to the control input to change the levels at which the switching occurs. When not in use, a 0.01 nano Farad capacitor should
be connected between pin 5 and ground to prevent noise coupled onto this pin from causing false triggering.
Connecting the reset (pin 4) to a logic low will place a high on the output of flip–flop. The discharge transistor will go on and the power amplifier will
output a low. This condition will continue until reset is taken high. This allows synchronization or resetting of the circuit's operation. When not in use,
reset should be tied to +VCC.

Thermoregulation And Temperature Essay
Introduction:
The surface temperature of a larger individual will increase more during exercise than that of a smaller individual. The purpose of this experiment is
to demonstrate the idea that body size may possibly have a direct correlation with the change of temperature within the body. It'll give insight to the
question: Does body size really have an effect of the change of temperature? In order to test this theroy there needs to be a clear understanding of the
components in the body that contribute to temperature. Those components are thermoregulation and thermoreceptors. Thermoregulation is the process
that allows all humans to maintain their core internal temperature, this is designed to keep the body regulated as well as allowing the

This means that the vacuole contents will more readily leak into the water in the test tube. The higher the temperature, the greater the disruption to the
plasma membranes and the more pigment will leak out in 30 minutes.
2. The factors controlled in this test are the ones that are the same from one group to another – the size of the beetroot cores (their surface area and
volume), the advance treatment of the beetroot cores, the volume of water in the test tubes, the pre–heating (or chilling) of the water in the test tubes
using the water baths, the length of time the cores spend in the water baths, the treatment of the cores after heating. The experiment could be made
more reliable by using more samples of beetroot, and by maintaining the temperature with thermostatically–controlled water baths.
3. The higher the temperature, the greater the amount of pigment released from the

The Temperature of Poetry
The Temperature of Poetry
Poetry is one of the stranger parts of the literary world. A poem can be anything, from a three–lined poem known as a haiku to a giant epic poem like
the "The Odyssey." They can be rhyming or non–rhyming, long or short, sensible or nonsensical. Even lyrics in songs can be considered poetry, seeing
as how they are rhyming and flow so well. The parameters for a poem are wide, the requirements few; but no matter what kind of poem you read,
from Homer to Doctor Seuss to John Mayer, symbolism is the driving force behind it all. Symbolism is the basis for almost every piece of poetry
written so far, barring some of the works of Doctor Seuss. One recurring piece of symbolism found throughout the literary world is the use of
temperature. The warmth of the sun or a comforting smile, the cold of night or a dark hospital room, temperature plays a part in many poems and
plays its part well. But the part it plays can vary from writer to writer, poem to poem. The three major uses of temperatures though are to show the
warmth of memory versus the harsh cold of reality, the warmth of comfort, and how warmth is used to show life and vitality while cold is used to
signify harshness and cruelty.
The first two poems to discuss are "I Wandered Lonely as a Cloud" by William Wordsworth and "Disabled" by Wilfred Owen. These two poems are
very different in their subject, but their usage of temperature in the form of memory gives them a common denominator. Both speak of

The Effect Of Temperature On A Chemical Reaction
Leonardo Cufone
Aim: to determine the effect of temperature on a chemical reaction.
Hypothesis: If the temperature (I.V.) of materials in the reaction are increased, the reaction time (D.V.) will decrease.
Variables: In this experiment, the temperature (in degrees Celsius) of the chemicals is the independent variable. To change thetemperature, the materials
are placed in a bath of water being heated by a hotplate.
The reaction time (in seconds) is the dependent variable of this experiment. This will be changed by the temperature of the chemicals, and as it is
affected by the independent variable it is considered the dependent variable.
The volume of chemicals (in mL) is the controlled variable of the experiment. As it will be the same in each trial and will not be changed, it is
considered the controlled variable. Another controlled variable is the equipment that is used. For each trial the same equipment is always used, and
therefore is also a controlled variable. The type of chemicals themselves are also controlled as for each trial they are the only chemicals used.
Safety: There are two potential hazards in this experiment.
Hydrochloric acid (HCl) has risks as it is a corrosive compound. Corrosive compounds, including HCl, can cause injuries such as burning and eating
away skin and eyes. To prevent such injuries, do not come into physical contact with HCl. Wear safety glasses, safety gloves and lab clothing.
Sodium thiosulfate (Na2S2O3) is risky as it is a toxic

Essay On Blowfly Temperature
Investigating the Effects of Temperature on the Rate of Respiration of Blowfly Larvae
This experiment was setup to investigate the effects of temperature on the rate of respiration of blowfly larvae.
Background Knowledge
The maggots involved in this investigation were blowflies at the larval stage of development, and they breathe through spiracles in the anterior and
posterior segments. The respiratory tracts are not as developed at this stage, as the organism is not capable of flight, and so it respires less oxygen
than an adult blowfly. They feed on dead organic matter. The respiration of an organism involves an intricate use of enzymes, and so some knowledge
about them is necessary. ... Show more content on Helpwriting.net ...
However, recent studies point towards the induced–fit hypothesis, which means that the substrate and the enzyme are not identical, yet in the presence
of the substrate the active site changes slightly, in order to make it a more "snug" fit. These theories pertain to a further point – the fact that an enzyme
is specific; the majority just have one possible type of substrate molecule. An increase in temperature affects the rate of an enzyme–controlled reaction
in two ways. First of all, the kinetic energy of all of the molecules is increased, thus increasing their speed. If they move faster, they have more
chance of an enzyme colliding with a substrate molecule, and so reacting. This is known as collision theory. The increase of rate can be determined by
the Q10 law. This states that for every 10 degrees in temperature in an enzyme–controlled reaction, the rate of that reaction will double, until 40 degrees
is reached. After this point, the enzyme may start to denature. This is when a certain factor affects the bonds holding the amino acids together, and they
start to break, eventually resulting in the enzyme unravelling. Generally this occurs between 40 and 60 degrees.

The Effect Of Temperature On Catechol Oxidase
Abstract: The Effects of Temperature on Catechol Oxidase. Lania Ellis, 2014, 102 Student Center Dr. San Marcos, TX 78666.
Temperature can affect the reaction of catechol oxidase by speeding up or slowing down the reaction. I was able to see what happened to the
absorbance after changing the temperature of the catechol oxidase solution. I did this by heating and cooling the solutions to measure the absorbances
in hot, cold, warm, and room temperature. Then the data was compared to see how the temperature effected the solution. The catechol oxidase solutions
reacted best in room temperature (twenty–three degrees Celsius) and the worst in the cold (zero degrees Celsius). I concluded that temperature really
does affect the way catechol oxidase reacts. Introduction: Starting out with some background information, I know that enzymes are biological catalysts.
The enzyme that I used for this experiment was potato juice. Enzymes make reaction rates go faster. They lower activation energy, making chemical
reactions. Temperature has an effect on canola cultivars. The higher temperature decreased stem diameter, but room temperature had thicker stems. So
I believe the same will happen for the catechol oxidase; the solution will react faster at room temperature. Other enzymes can also have different effects
such as the enzyme in cattle serum. The enzyme lost activity in room temperature. With that being said room temperature can also be detrimental with
specific enzymes. Fungus also

BACKGROUND
As energy flows from a liquid, its temperature drops. The entropy, or random ordering of its particles, also decreases until a specific ordering of the
particles results in a phase change to a solid. If energy is being released or absorbed by a substance remaining at the same temperature, this is evidence
that a dramatic change in entropy, such as a phase change, is occurring. Because all of the particles of a pure substance are identical, they all freeze at
the same temperature, and the temperature will not change until the phase change is complete. If a substance is impure, the impurities will not lose
energy in the ... Show more content on Helpwriting.net ...
8. Set up the container for the hot–water bath. Attach two ring clamps, one above the other, to the second ring stand beneath the test tube assembly.
Place a wire gauze with ceramic center on the lower ring. Set a third 600 mL beaker, which should be empty, on the gauze and raise the beaker toward
the test–tube assembly until it surrounds nearly one–half of the tube's length. The beaker will pass through the ring clamp without gauze, and the test
tube should not touch the bottom or sides of the beaker. The top clamp keeps the beaker from tipping when the beaker is filled with the hot water.
PART 2–MELTING A SOLID: QUICK TEST
9. Check the temperature of the water for the hot–water bath. When it is 85В°C, turn off the burner or hot plate. If the temperature is already greater
than 85В°C, shut off the burner or hot plate, and add a few pieces of ice to bring the temperature down to 85В°C. Then, using beaker tongs remove
the beaker of hot water from the burner. Using tongs or hot mitts carefully pour the water into the empty beaker until the water level is well above the
level of the solid inside the test tube. Set the empty beaker on the counter. You will use it again in step 20.
10. Begin timing. The second the water is poured, one member of the lab group should begin timing, while the other reads the initial temperatures of
the bath with one thermometer and sample with the other thermometer.

The Effect Of Temperature On The Enzyme Peroxidase
The Effect of Temperature on the Enzyme Peroxidase The objective of this experiment is to explore the effect of temperature on the enzyme
peroxidase. To comprehend the effect that temperature can have on enzymes, specifically peroxidase, one must understand what enzymes are and what
their function is. Enzymes are proteins that are found in cells that function as catalyst (Ms. Chang's Enzyme Notes). What is meant by this is that
enzymes increase the speed of chemical reactions without changing the chemical equilibrium between reactants and products or becoming consumed
or permanently modified by the reaction through lowering the activation energy barrier (Enzymes). Enzymes are necessary in order to sustain life
because without them, the chemical reactions that take place in our cells would occur far too slowly (Ms. Chang's Enzyme Notes). In order to
generate chemical reactions, enzymes must bind to a substrate. A substrate is a specific reactant that an enzyme acts upon in order to generate
product. A substrate binds to the active site on the enzyme, which is a groove or cavity on the surface of the enzyme in which the substrate flawlessly
fits. Active sites are typically composed of amino acids from various portions of the polypeptide chains that are drawn together in the tertiary structure
of the folded protein (Enzymes). Each type of enzyme can only bind with specific substrates, because it is critical that the substrate and the active site
of the enzyme align

Describe the effect of heat on the motion of particles, and explain changes of state using the particle model of matter.
There are four basic components for thermal energy (heat): 1. All matter is made up of tiny particles called atoms. These can only be seen with special
microscopes. 2. The atoms are always moving – they all have kinetic energy. 3. The particles have space between them. Different states of matter have
different amounts of space. 4. Adding heat (energy) to matter makes the particles move more quickly. Since faster moving things have more kinetic
energy, adding heat increases the energy of the particle. 5. Cooling it down decreases the amount of kinetic energy and slows the movement down.
Distinguish between heat and temperature, and explain temperature using the concept of kinetic energy and the particle model of matter.
Temperature: the average kinetic energy of individual atoms and molecules
Heat Energy: The collection of random molecules in action.

They can be used to detect liquid, gases or solids over a wide range of temperatures.
Non –contact temperature sensor:
Convection and radiation is used in these types of temperature sensors to monitor change in temperature. They can be used to detect gases and liquids
that emit radiant energy as heat rises and cold settles to the bottom in convection currents or detect radiant energy being transmitted from an object in
the form of infrared radiation.
Two basic types of contact or non–contact temperature sensors can be divided into following groups of sensors i.e. electromechanical, resistive and
electronic.
Thermostat:
It is contact type electro–mechanical temperature sensor or switch which basically consists of two different metals such as nickel copper ,tungsten or
aluminium etc., that are bonded together through riveting, brazing or welding to form a Bi–metallic strip. The different linear expansion rates of two
different metals produce a mechanical bending moment when strip is subjected to heat. It shows bending moment in opposite direction when subjected
to cold environment. The metal with large coefficient of expansion is at the outer side of the curve formed during heating and vice versa.
The bi–metallic strip can be used as an electrical switch or a

Graph's Effect On Water Temperature
Graph 1 suggests that, during the 2002–03 El NiГ±o event, the water temperature at 50 and at 100 meters below sea surface remained similar from
July 18 to September 29 of 2002; however, the water temperature at 100 meters below the surface was slightly colder. After that date range, the water
temperature at 100 meters below the surface decreased by в‰€5 В°C while thetemperature at 50 meters below the surface remained constant
throughout the entire length of time. The water temperature at 200 meters below the surface remained colder than at 50 and 100 meters below sea
level and continued to decrease at a gentle slope from July 18 to December 5, by в‰€5 В°C. A temperature increase of в‰€2 В°C was observed from
December 5 to January 16.
As indicated by Graph 2, the water temperatures at 50 and 100 meters below sea level differed by в‰€4В±1 В°C from each other, and decreased at
similar slopes. The temperature at 100 meters below sea level remained colder than that at a 50–meter deepth. The water temperature at 200 meters

The Celsius Scale Of Temperature
Anders Celsius was born in 1701 in Uppsala, Sweden. He created the Celsius scale of temperature in 1742. When he created the Celsius scale, 0
degrees was the boiling point of water and 100 degrees the freezing point. The Celsius system stayed this way until Jean Pierre Cristin, a french man,
flipped the Celsius system to how it is today. That is with 100 degrees being boiling point and 0 degrees being the freezing point. Anders Celsius
died in 1744. He was 42 years old. Celsius had made a great step in scientific work with the Celsius scale. When the Celsius scale was first invented,
fixed temperature points were unheard of, meaning that no one understood that one temperature was the boiling or freezing point of every cup of water.

The transportation industry wants to know how to melt ice on the road faster. The food industry wants to keep things frozen longer during
transportation. The freezing and melting point of a liquid or solid, depending, may seem like it would be the same science, but it is not. Small
differences can be observed. One point is that you can not heat an object above melting point without it melting. It is, however, possible to cool some
liquids to a temperature below their freezing point without them turning solid. This process is called supercooling. Supercooling a liquid is possible
because particles in a solid become packed in a normal structure that is a characteristic of a certain substance. Some solids form easily. Other solid
substances do not form easily. Because it is hard to heat metals to a temperature above melting point,and easy to cool them to a point below freezing,
melting point becomes a distinguishing factor of the metals.
The boiling point of a liquid is when a liquid is heated to such a temperature that the vapor pressure is enough so that bubbles form inside the liquid.
At the boiling point liquid begins to turn to gas. A liquid will boil until all of the liquid has evaporated. The normal boiling point of water, as stated
earlier, is 100В°C. But, as altitude increases, the boiling point is lowered.
Adding salt to a frozen matter is to upset the balance between freezing and melting. The salt causes fewer molecules to

Temperature And Solubility
At what temperature is more KCl able to dissolve: 40В°C or 90В°C?
90 C since with the KCl we found that the higher the temperature the more likely the substance is to have greater solubility.
How is temperature related to the solubility of a salt? Explain your answer.
Solubility increases with temperature because the increase in kinetic energy allows the solvent molecules to break apart the solute molecules that are
held together by intermolecular attractions.
Which salt is more soluble, KCl or NH4Cl? Explain your answer.
NH4Cl since the data shows us that it requires less heat than KCl to fully dissolve.
Why is it important to not allow the test solutions to boil?
Because if it boils then some of the solvent will be lost
