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

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

The ratio of specific heats at constant pressure and at constant volume is $\gamma$. To find out the degree of freedom,the expression is

If hydrogen gas is heated to a very high temperature,then the fraction of energy possessed by gas molecules corresponding to rotational motion is ...........

At standard temperature and pressure $(STP)$,the density of a gas is $1.3 \ kg/m^3$ and the speed of sound in the gas is $330 \ m/s$. The degree of freedom of the gas is:

The internal energy of one mole of a rigid diatomic gas at absolute temperature $T$ is
