Often we find that different phases of pure substances can exist in equilibrium with one another. Let us consider an important gedankenexperiment (Latin-German for "thought experiment") in which we boil water. Ordinary water boiling is...

Students investigate the structure and parts of the atom, and learn about atomic mass and atomic number. They also explore the differences among solids, liquids, gases, and plasma.

A brief explanation of determining the temperature and density at which the critical point of nuclear matter is located.

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

Use this resource to learn about the three different phases of water; solid, liquid, and gas. What happens to water as it changes into a solid or gas? Includes short and easy to do activity.

Five exemplary chemistry lessons about the three states of matter complete with handouts and animations.

A discussion of the variety of forces which hold molecules together. The relative strengths of these forces for the various states of matter is discussed. The effect of such forces on the boiling points and other phase change...

[Free Registration/Login Required] In this interactive you will move the red dot below each flask to observe how particles move in each different phase of water. You will need a sign-in to access this media, but it will be well worth...

Printable classroom-ready worksheets for a series of simple-to-implement experiments about the states of matter.

The question: "What would the triple point of water truly look like?" is discussed and explained. The phases of matter are described.

This tutorial helps students understand the Kinetic Theory, which explains the effects of temperature and pressure on matter as it goes through phase changes.

At this resource discover the difference between solids, liquids, and gases. Practice what you just learned with included review questions.

Students will practice the technique of chromatography by separating a mixture of FD&C dyes. Questions related to the experiment along with the answers are available for use by the teacher.

Discusses the changes of state that can occur for the three different types of matter (solids, liquids, and gases) and different types of heat energy that have been defined by scientists.

Explore the different states of matter while creating glue.

Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.

Discover how freezing works, when the change of state moves from liquid to solid.

Wikipedia offers a brief description of the term, "Melting point," including hyperlinked terms.

Explore the movement of the molecules in a solid.

Percy Julian and Josef Pikl used the fact that melting point-the temperature at which a substance changes from a solid to a liquid-is a characteristic property of a substance to prove that the British chemist Robert Robinson could not...

Is it a solid or a liquid? In this activity, students will handle a mystery substance that has qualities of both a solid and a liquid while learning about phases. They will manipulate the substance, record any observations they...

In this activity, students' will investigate what causes phase changes in matter.They use a temperature sensor to measure the temperature of a substance and identify visual clues to the phase changes.

This PDF is fill in the blank notes, activities and graphic organizers on kinetic molecular theory.

The late prehistoric rock-art sites of the Mediterranean seaboard of the Iberian peninsula form an exceptionally large group. Here the way of life during a critical phase of human development is vividly and graphically depicted in...
