The mean kinetic energy per degree of freedom of gas molecules is:

The number of rotational degrees of freedom of a monatomic molecule is

$A$ diatomic gas consisting of rigid molecules is at a temperature of $87^{\circ} C$. If the moment of inertia of the rotating diatomic rigid molecule is $2.76 \times 10^{-39} \text{ g cm}^2$,then the rms angular speed of the molecule is (Boltzmann constant $= 1.38 \times 10^{-23} \text{ J K}^{-1}$).

$A$ diatomic molecule has how many degrees of freedom?

How many degrees of freedom does a diatomic gas have due to its translational motion?

Write the degree of freedom for a polyatomic gas.
