If n is the number density and d is the diameter of the molecule, then the average distance covered by a molecule between two successive collisions (i.e., mean free path) is represented by:

If the root mean square speed of oxygen molecules at 300 K is approximately 483 m/s, what is the rms speed at 1200 K?

The most probable speed (Cmp) of a gas molecule is given by which expression?

The mean kinetic energy per molecule for a rigid diatomic gas at absolute temperature T is given by (where kB is Boltzmann's constant):
