Learn about the changing states of matter.

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...

Learn about the phases of matter in this section of a college textbook. Section defines the phases of matter and discusses how to interpret a phase diagram. Also explored is partial pressures and Dalton's Law. Section also includes...

The heat of vaporization along with several other thermal properties are explained. Sample problems are given. Illustrations.

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