4.solids, liquids, and gases
The document defines the three states of matter - solids, liquids, and gases. Solids have a fixed shape and size, liquids flow and take the shape of their container, while gases have no definite shape or volume. It provides examples like water changing between solid (ice), liquid (water), and gas (steam) states through melting, evaporation, condensation, and freezing. The document also describes an experiment to observe condensation on a cold glass.
Units 2 and 3
This document contains a review of units 2 and 3 which cover:
1) Converting between different units of measurement for mass, length, area and volume.
2) Calculating density for different materials given their mass and volume.
3) Explaining the kinetic theory of matter and how temperature, pressure and container size affect the movement and properties of gas particles.
4) Defining processes related to changes in states of matter like expansion/contraction, evaporation and boiling.
Jeopardy 1
The document discusses various properties of the three main states of matter: solid, liquid, and gas. It addresses how solids have a fixed shape while liquids do not, how melting occurs at the melting point when a solid turns into a liquid, and how boiling is the process where a liquid turns into a gas at the boiling point.

This document summarizes the differences in density between water and alcohol. Water and alcohol can have the same volume but different masses because their densities are not the same. The density of a substance depends on factors like its temperature, mass, and volume. When measuring 1 liter of water and 1 liter of alcohol, the water has a mass of 1000 grams while the alcohol has a mass of 790 grams. This is because the molecules in water are more densely packed than alcohol molecules, even when the volumes are the same.
Powerpoint
The document discusses the three states of matter: solids, liquids, and gases. It describes their key properties - solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have no definite shape or volume. Examples of each state are provided.
states of matter
The document discusses the three states of matter - solids, liquids, and gases. It explains that in solids, molecules are tightly packed together and have a definite shape and volume. In liquids, molecules are less tightly bonded than in solids and take the shape of their container but have a definite volume. Gases have loosely bonded molecules that expand to fill their entire container with no definite shape or volume. Matter can change states from solid to liquid to gas as temperature increases, and from gas to liquid to solid as temperature decreases.
States of matter anna
The document discusses the five states of matter - solids, liquids, gases, plasma, and Bose-Einstein condensate. Gases are compressible and have particles that can move freely past one another. Liquids flow easily and take the shape of their container but maintain a constant volume. Solids have a fixed shape and volume, and their particles cannot move past one another. Plasma is an ionized gas, and Bose-Einstein condensate is a state of matter that occurs at extremely low temperatures near absolute zero.
States of matter 2010
1. The document discusses states of matter and gas laws. It provides descriptions of solids, liquids, gases and plasmas, focusing on how particle movement differs between each state.
2. Gas laws including Boyle's law and Charles' law are introduced. Boyle's law states that for a fixed amount of gas at constant temperature, volume and pressure are inversely related. Charles' law states that for a fixed amount of gas at constant pressure, volume and temperature are directly related.
3. Examples are given to demonstrate these gas laws, such as how the volume of balloons changes under differing pressures in Boyle's law experiment, and how bicycle tire pressure should be adjusted for temperature changes according to Charles' law.

The document describes an experiment demonstrating convection in liquids. Cold blue water is placed in a bottle and covered with foil, while hot red water is placed in a separate bottle. The bottles are placed in a larger container of room temperature water. Over time, the cold blue water sinks to the bottom as it flows out, while the hot red water rises to the top as it flows out, clearly showing that hot liquids rise and cold liquids sink due to differences in density.

3.10 all change
This document describes changes of state between solids, liquids, and gases. It explains that:
- Solids melt when heated and particles gain enough energy to overcome bonding forces, becoming a liquid. Different substances have different melting points depending on bonding strength.
- Gases condense when cooled, as slower particle motion allows intermolecular forces to attract particles together into a liquid.
- Liquids evaporate when heated, as faster particle motion overcomes bonding forces and particles escape as a gas. Evaporation leads to boiling when it occurs throughout the liquid.
- The boiling point of a liquid depends on surrounding air pressure, with lower pressure resulting in a lower boiling point.
Whatis matter 1
This document discusses the three states of matter: solids, liquids, and gases. It defines each state and provides examples. Solids maintain their shape and size, liquids take the shape of their container, and gases have no definite shape and fill their container. The document also notes that some materials can exist in more than one state of matter, and that matter can change states through processes like melting, freezing, and evaporation. It uses water as an example, pointing out that it can exist as ice (solid), liquid water, or water vapor (gas).
3 states of matter !!!!!!!
This document discusses the three states of matter: solids, liquids, and gases. It provides examples of each state and describes their key properties. Solids have a definite shape and volume, with particles that are close together and move slowly. Liquids have a definite volume but not shape, with particles that can slide past one another. Gases have no definite shape or volume, and their particles move quickly and are far apart with empty space between them. Examples are given for common substances that exist in each state of matter.
Text: three phases of matter
Matter exists in three phases: solids, liquids, and gases. Solids have a fixed shape and volume, with molecules packed closely together, as seen in pencil. Liquids have a fixed volume but take the shape of their container, like water. Gases easily change their shape and volume, with particles spreading apart, such as air in a balloon. The key difference between the three phases is the arrangement of molecules - closely packed in solids, somewhat free in liquids, and freely moving in gases.
Class 9 SCI CH 1 - Session 3
The document contains questions and answers about different states of matter and their properties. It also includes questions about temperature conversions between Celsius, Fahrenheit and Kelvin scales, as well as evaporation and how putting wet clothes on someone's forehead can lower a fever by evaporative cooling.
states of matter
This document discusses the three states of matter: solid, liquid, and gas. It defines each state and their key properties.

2) The particles that make up matter are in constant motion and attract each other, but can change arrangement depending on temperature.
3) Matter can change between solid, liquid, and gas states through processes like melting, boiling, evaporation, condensation, and sublimation caused by changes in temperature and pressure acting on the particles.
Describing Matter for Kids
This document discusses the properties and states of matter. It describes matter as having properties like mass, size, shape, color and texture. Matter can exist in three states - solid, liquid, or gas. Solids have a definite shape and size, liquids take the shape of their container but have mass, and gases have no definite shape but do occupy space. The document provides examples of different materials and discusses the characteristics of the three states of matter. It also discusses recycling and gives reasons why recycling is important.
Water density
The document discusses how the density of substances can change with temperature. It notes that most substances contract and become more dense when cooled, while expanding and becoming less dense when heated. An exception is water, which is more dense in its liquid form than as a solid (ice), allowing ice to float. This unique property allows plants and animals to survive winter freezing. The document also discusses how salt water is denser than fresh water.
States of matter
There are three states of matter: solids, which are hard objects like rocks; liquids, which are flowy and take the shape of their container like water and soda; and gases, which have no fixed shape and are between solids and liquids, like air.
Why does it seems that the sun move
The document discusses the motion of the Earth and how it causes day and night as well as apparent motion of the sun. It explains that the Earth rotates on its axis every 24 hours, which causes one side of the Earth to face the sun while the other side faces away, creating day and night. It also discusses how the Earth revolves around the sun over the course of 365 days.

How does soil affect living things
The document discusses the formation and composition of soil. It explains that soil is formed over long periods of time through the weathering and breakdown of rocks and the decomposition of dead plants and animals. The soil is made up of weathered rocks, humus from decomposed materials, and minerals. It has distinct layers with varying properties including the topsoil, subsoil, and bedrock below. Different types of soil like sand, silt, and clay are determined by the size of particles. Loam is an ideal soil made of a mixture of these. The document emphasizes the importance of protecting soil as a vital natural resource.
How do we use air & water
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. and salt water found in oceans. It then outlines several key steps in treating water from rivers and lakes, such as allowing solids to settle, filtering through layers of sand and gravel, adding chemicals to kill harmful organisms, and pumping the clean water for distribution.
Presentation1
Natural disasters and diseases can change environments and affect living organisms. Floods occur when heavy rain falls in a short period, covering land with water, while droughts are long periods without rain that can dry up rivers and lakes, increasing wildfire risks that damage plant and animal habitats. Diseases from mold, bacteria, and mildew also easily spread in environments and harm living things, with one infected tree having the potential to destroy an entire forest.
Plants needs
Plants need five things to survive and grow: oxygen from the air, water, nutrients found in soil, space to grow freely, and sunlight. Fruits were once living parts of plants but become non-living when picked after ripening.
Adaptation
Organisms adapt traits that help them survive in their environments. Some examples of adaptations include camouflage, mimicry, nocturnal behavior, hibernation, and migration. Camouflage allows animals to blend into their surroundings and hide from predators or to ambush prey. Mimicry enables some animals to resemble other organisms for protection. Nocturnal habits, hibernation, and migration are ways animals adapt to changes or shortages in their environments like weather changes or lack of food sources. Plants also exhibit adaptations like deep roots that help them survive in difficult conditions.
Volume
Liquids and gases take the shape of their container, unlike solids which do not. Volume is defined as the space occupied by matter, and can be measured using tools like measuring cups. Common units for measuring volume include liters and milliliters.
How do ecosystems compare
The document compares different ecosystems by describing their climates and key characteristics. Tropical rainforests have hot, wet climates all year and contain the greatest diversity of plants and animals. Temperate forests' climates change with warm summers and cold winters, and they receive less rain than rainforests. Wetlands are covered in water most of the year, found along rivers and coasts, and help absorb flood waters and cleanse dirty water. Oceans are the largest ecosystem and most living things inhabit the sunlit, shallow areas near the surface.
Food chains and food webs
Food chains and food webs show how energy passes from one organism to another as they eat each other. A food chain tracks the flow of energy starting with a plant that gets its energy from the sun, then to an animal that eats the plant, then another animal that eats the first animal. A food web is more complex, showing that organisms can be part of multiple food chains as some animals eat different plants and other animals.
Herbivores, carnivores and omnivores
This document discusses three categories of animals based on their diets: herbivores, which eat only plants; carnivores, which eat only meat; and omnivores, which eat both plants and meat. Herbivores include deer, rabbits, elephants, turtles, monkeys and giraffes. Carnivores include lions, crocodiles, snakes and eagles. Omnivores include bears, raccoons, pigs, and humans.
Ecosystem
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.
Habitat 180115095217
This document discusses habitats and the different animals that live in each one. It explains that a habitat provides all the needs for animals to survive, including food, water and shelter. It then identifies the five main habitats as ocean, forest, desert, grasslands, and Antarctica, and provides some example animals for each one. The habitats differ in their characteristics such as being wet or dry, hot or cold, containing trees, grass or snow.
Frog life cycle
The frog life cycle consists of 5 stages - eggs are laid in water, tadpoles hatch with gills and swim, tadpoles grow legs and lungs and become young frogs, young frogs resemble adult frogs and live on land, frogs undergo complete metamorphosis as each stage looks physically different.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
