According to the law of equipartition of energy, the molar specific heat of a non-rigid diatomic gas at constant volume is

If the ratio of specific heats of a gas at constant pressure and at constant volume is $\gamma$,then the number of degrees of freedom of the rigid molecules of the gas is

The number of translational degrees of freedom for a diatomic gas is

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

Given below are two statements:
Statement $I :$ In a diatomic molecule,the rotational energy at a given temperature obeys Maxwell's distribution.
Statement $II :$ In a diatomic molecule,the rotational energy at a given temperature equals the translational kinetic energy for each molecule.
In the light of the above statements,choose the correct answer from the options given below:

For a gas,$\gamma = 7/5$. The gas may probably be
