Properties of Gases: matter at its simplest
1- Observable properties of gasesClick one of the six lesson titles immediately below; you can also go directly to any sub-section within a lesson.
atmospheric pressure and the barometer
2- Ideal gas: the basic laws
The law of Charles and Gay-Lussac
3- Moles and mixtures

Kinetic-molecular interpretation of gas properties
Some consequences of random molecular motion
Diffusion: random motion with direction
Density fluctuations: why the sky is blue
Distribution of gas molecules in a gravitational field
5- More kinetic molecular theory("KMT-classic")
