The ratio of the average translational kinetic energies of hydrogen and oxygen at the same temperature is

The total momentum of the molecules of $1 \,gm$ $mol$ of a gas in a container at rest at $300 \,K$ is

The average translational kinetic energy of a molecule in a gas becomes equal to $0.69 \ eV$ at a temperature of about,[Boltzmann's constant $= 1.38 \times 10^{-23} \ J \ K^{-1}$] (in $^{\circ} C$)

If the average kinetic energy of $O_2$ (molar mass $32$) is $0.048 \ eV$,what is the average kinetic energy of $N_2$ (molar mass $28$) at the same temperature (in $eV$)?

If $E$ is the kinetic energy per mole of an ideal gas and $T$ is the absolute temperature,then the universal gas constant is given as

Two gases are at absolute temperatures $300 \ K$ and $350 \ K$ respectively. The ratio of the average kinetic energy of their molecules is:
