gases 101 - how can we describe gaseous systems macroscopically and microscopically?
DESCRIPTION
The state of an ideal gas can be calculated using the ideal gas law. The composition of gas mixtures can be given using Dalton's partial pressures. Microscopically a gas can be described by Maxwell-Boltzmann theory with the parameters average speed and mean free path being most important. Deviatons from the ideal behavior can be quantified using the van-der-Waals equation, which explains why at the critical point a gas behaves only "3/8 idealy".
