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

Under standard conditions,the density of a gas is $\frac{1400}{1089} \ kg \ m^{-3}$ and the speed of sound propagation in it is $330 \ ms^{-1}$. The number of degrees of freedom of the gas molecules is:

The ratio of the kinetic energy of a diatomic gas molecule at a high temperature to that at $NTP$ is:

$A$ monoatomic gas molecule has

An ideal gas has molecules with $5$ degrees of freedom. The ratio of specific heats at constant pressure $(C_p)$ and at constant volume $(C_v)$ is

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