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):

The absolute temperature of an ideal gas is increased from 120 K to 480 K. If at 120 K, the root mean square velocity of the gas molecules is u, then at 480 K it becomes:
