A study guide for concepts related to thermal energy.

Classroom activity helps students understand evaporation.

Help the Phantom choose a material and observe the changes at different temperatures in the molecule chamber. What happens to the elements or molecules as the temperature changes?

A lengthy set of lecture notes on the topics of thermal expansion and heat absorption. The concept of specific heat capacity is explained and numerical examples are discussed. Heats of transformation (fusion, vaporization) are explained...

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and entropy. The subject, absolute entropies, is discussed in addition to the third law of thermodynamics, phase...

Learn what affect changing temperature has in regards to chemical reactions.

The meaning of vapor pressure is introduced. The distinction between evaporation and boiling is discussed and explained. The reason that liquids undergo vaporization is explained.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

An exhaustive set of "lecture notes" on various topics in thermal physics (including thermal expansion). Explanations are well done and more interesting than most. Includes both a mathematical and conceptual treatment of topics. Humor,...

You know that water can exist in three separate phases: solid (ice), liquid (water), and vapor (steam). To change from one phase to another, you simply add (or remove) heat. When water boils, what happens to molecules (for example sugar...

A collection of video lectures from a general chemistry class for high school students. Lectures cover topics such as equilibrium, thermochemistry, electrochemistry, and acids and bases with forty-four lectures. Lectures vary in length...

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.

An exhaustive list of equations and formulas which are commonly used in thermal physics (including equations for triple point). Equations are organized according to category. Meaning of the symbols is clearly stated.

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...
