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

At constant volume,the temperature of a gas is increased. Then:

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

The average kinetic energy of $H_2$ molecules at $300 \ K$ is $E$. At the same temperature,the average kinetic energy of an $O_2$ molecule is:

The average kinetic energy of a gas molecule at $27^oC$ is $6.21 \times 10^{-21} \, J$. Its average kinetic energy at $227^oC$ will be

The relation between the gas pressure $P$ and average kinetic energy per unit volume $E$ is
