The kinetic energy,due to translational motion,of most of the molecules of an ideal gas at absolute temperature $T$ is proportional to:

Absolute temperature can be calculated by

$A$ vessel of volume $10 \text{ liters}$ is filled with $H_2$ gas. The total average translational kinetic energy of its molecules is $4.5 \times 10^5 \text{ J}$. The pressure of hydrogen in the vessel is

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:

$A$ gas exerts pressure on the walls of a container because the molecules .......

At $27^{\circ}C$ temperature,the kinetic energy of an ideal gas is $E_1$. If the temperature is increased to $327^{\circ}C$,then the kinetic energy would be:
