The translational kinetic energy of the molecules of a gas at absolute temperature $T$ can be doubled by:

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

$A$ sealed container with negligible coefficient of volumetric expansion contains helium (a monoatomic gas). When it is heated from $300\, K$ to $600\, K,$ the average kinetic energy $(K.E.)$ of helium atoms is

$A$ flask contains argon and oxygen in the ratio of $3: 2$ in mass and the mixture is kept at $27^{\circ} C$. The ratio of their average kinetic energy per molecule respectively will be ...........

The average kinetic energy of a gas at $-23^{\circ}C$ and $75 \, cm$ pressure is $5 \times 10^{-14} \, erg$ for $H_2$. The mean kinetic energy of $O_2$ at $227^{\circ}C$ and $150 \, cm$ pressure will be:

The relationship between the kinetic energy per unit volume $(E)$ and the pressure $(P)$ for a given gas is .....
