1. This document discusses the kinetic molecular theory and properties of ideal gases. It introduces concepts such as average kinetic energy, Maxwell speed distribution curves, and the ideal gas law.
2. Several gas laws are described, including Boyle's law, Charles' law, Avogadro's law, and Dalton's law of partial pressures. Standard temperature and pressure is defined.
3. Deviations from ideal gas behavior occur at high pressures due to intermolecular forces and the non-negligible volume of gas particles. Real gases behave more ideally at lower pressures.

Organic compounds are almost 60% of all compounds. because of carbons tendency to form a compound as it has more than1 electron(4electrons) to form covallent compounds. SO a wide range of everything we eat is formed from carbon and hydrogen, which is the second important element to form organic compounds.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
The Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2. This theory presents physical properties of gases
in terms of the motion of individual molecules.
• Average Kinetic Energy Kelvin Temperature
• Gas molecules are points separated by a great
distance
• Particle volume is negligible compared to gas volume
• Gas molecules are in rapid random motion
• Gas collisions are perfectly elastic
• Gas molecules experience no attraction or repulsion

6. The ideal gas law illustrates the relationship
between pressure, volume , temperature and moles.
The formula for the ideal gas law is
In this formula:
P = Pressure
V = Volume
n = Moles
T = Temperature
R = The Ideal Gas Constant
6
7. The gas constant (also called
the universal gas constant, molar
gas constant or ideal gas
constant) is a physical constant,
denoted as R, which appears in
many fundamental equations in
physics, engineering and other
sciences, such as the ideal gas
law and other equations of state.
Currently, the most accurate
value of R is 8.3144621.

8. Boyle’s Law describes the inverse proportional relationship
between pressure and volume at a constant temperature and
a fixed amount of gas. This law came from a manipulation of
the Ideal Gas Law.
This equation would be ideal when working with problem
asking for the initial or final value of pressure or volume of a
certain gas when one of the two factor is missing.
8
9. Charles's Law describes the directly proportional
relationship
between the volume and temperature (in Kelvin) of a fixed
amount of gas, when the pressure is held constant.
This equation can be used to solve for initial or final value
of
volume or temperature under the given condition that
pressure and the number of mole of the gas stay the same.
9
10. Volume of a gas is directly proportional to the amount of as
at a constant temperature and pressure.
Avogadro's Law can apply well to problems using Standard
Temperature and Pressure, because of a set amount of
pressure and temperature.
10
11. Given a constant number of mole of a gas and an
unchanged volume, pressure is directly proportional to
temperature.
Boyle's Law, Charles' Law, and Avogadro's Law and
Amontons's Law are given under certain conditions so
directly combining them will not work. Through advanced
mathematics (provided in outside link if you are
interested), the properties of the three simple gas laws
will give you the Ideal Gas Equation.
11
12. Standard condition of temperature and pressure is known as STP.
Two things you should know about this is listed below.
The universal value of STP is 1atm (pressure) and 0 C
degree. Note that this form specifically stated 0 C degree,
not 273 Kelvin, even thought you will have to convert into
Kelvin when plugging this value into the Ideal Gas
equation or any of the simple gas equations.
In STP, 1 mole of gas will take up 22.4 L of the volume of
the container.

13. In a mixture of gases the total pressure, Ptot, is the
sum of the partial pressures of the gases:
Dalton’s law allows us to work with mixtures of
gases.

• For a two-component system, the moles of
components A and B can be represented by the
mole fractions (XA and XB).
• What is the mole fraction of each component in
a mixture of 12.45 g of H2, 60.67 g of N2, and
2.38 g of NH3?

Mole fraction is related to the total pressure by:
On a humid day in summer, the mole fraction
of gaseous H2O (water vapor) in the air at 25°C
can be as high as 0.0287. Assuming a total
pressure of 0.977 atm, what is the partial
pressure (in atm) of H2O in the air?
16. Deviations result from assumptions about
ideal gases.
1.Molecules in gaseous state do not exert
any force, either attractive or
repulsive, on one another.
2.Volume of the molecules is negligibly
small compared with that of the
container.
16
17. At higher pressures, particles are much closer
together and attractive forces become more
important than at lower pressures.
17
18. The volume taken up by gas particles is
actually less important at lower pressures
than at higher pressure. As a result, the
volume at high pressure will be greater than
the ideal value.
