When heat is supplied to an Argon gas,what is the percentage distribution of the energy into translational and rotational kinetic energy?

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

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

At a certain temperature,the degrees of freedom per molecule for a gas is $8$. The gas performs $150 \; J$ of work when it expands under constant pressure. The amount of heat absorbed by the gas will be $..... \; J$.

State and explain the law of equipartition of energy.

$500 \text{ g}$ 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].
