The kinetic energy per gram mole for a diatomic gas at room temperature is:

The mean kinetic energy of $1 \, mole$ of gas per degree of freedom (on the basis of kinetic theory of gases) is

What is the degree of freedom?

The ratio of total energy of all molecules of one mole of $O_2$ to the total energy of all molecules of two moles of $He$ at the same temperature 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 mean rotational kinetic energy of a diatomic molecule at temperature $T$ is
