The kinetic energy of one mole of a gas at $300 \, K$ is $E$. If the kinetic energy at $400 \, K$ is $E'$,then what is the ratio $E'/E$?

$A$ cylinder of capacity $20 \text{ litres}$ is filled with $H_2$ gas. The total average kinetic energy of translatory motion of its molecules is $1.5 \times 10^5 \text{ J}$. The pressure of hydrogen in the cylinder is

An ideal gas in a container of volume $500 \text{ c.c.}$ is at a pressure of $2 \times 10^5 \text{ N/m}^2$. The average kinetic energy of each molecule is $6 \times 10^{-21} \text{ J}$. The number of gas molecules in the container is:

The average kinetic energy of $H_2$ at $300 \, K$ is $E$. What is the average kinetic energy of $O_2$ at the same temperature?

The value of universal gas constant is $8.3\, J/mol/K$. The mean kinetic energy of $32\, g$ of oxygen at $-73^{\circ}C$ will be ...... $J$.

The pressure of a gas is $6 \times 10^4 \ N/m^2$. What will be the kinetic energy per unit volume of the gas molecules?
