The mean rotational kinetic energy of a diatomic molecule at temperature $T$ is

The number of rotational degrees of freedom of a diatomic molecule is:

Calculate the degree of freedom of a diatomic gas.

$500 \text{ g}$ of a diatomic gas is enclosed at a pressure of $10^5 \text{ N m}^{-2}$. The density of the gas is $5 \text{ kg m}^{-3}$. The energy of one mole of the gas due to its thermal motion is [consider the gas molecule as a rigid rotator].

What is the degree of freedom of a honey bee flying in a room?

Energy of $10$ non-rigid diatomic molecules at temperature $T$ is:
