Gases
In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both...

Practice Problem: Graham's Law of Effusion
We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...

Kinetic Molecular Theory and its Postulates
We learned about ideal gases and the ideal gas laws, and we briefly touched on kinetic molecular theory, which puts these laws in context. But let's now go through this theory more rigorously, analyzing each postulate one at a time.

The Kinetic Theory
Amaze class members with the fact that solids, liquids, and gases all have the same particles. Kinetic theory explains how the particles loosen their bonds when given energy. Solids become liquids and liquids become solids.
