The pressure exerted by the gas on the walls of the container is because:

An ideal gas occupies a volume of $2\, m^3$ at a pressure of $3\times10^6\, Pa$. The energy of the gas is

At $...... ^\circ C$ temperature,the mean kinetic energy of ${O_2}$ molecules will be the same as that of ${H_2}$ molecules at $-73^\circ C$.

$A$ box contains $N$ molecules at temperature $T_1$ and pressure $P_1$. If the number of molecules in the box is doubled but their total kinetic energy remains unchanged,what are the new pressure $P_2$ and temperature $T_2$?

The kinetic energy of translation of the molecules in $50 \text{ g}$ of $\text{CO}_2$ gas at $17^{\circ}\text{C}$ is: (in $\text{ J}$)

The average translational kinetic energy of the oxygen molecules at a temperature of $127^{\circ} C$ is (Boltzmann constant $= 1.38 \times 10^{-23} \,J \,K^{-1}$)
