If the intermolecular forces in 4.5 kg of water at STP vanish, what volume will the water molecules occupy?

The kinetic energy of one gram molecule of a gas at normal temperature and pressure is $\left( {R = 8.31\;J/mol - K} \right)$

Oxygen and hydrogen are at the same temperature $T$. The ratio of the mean kinetic energy of oxygen molecules to that of the hydrogen molecules will be

Vessel $A$ is filled with hydrogen while vessel $B,$ whose volume is twice that of $A,$ is filled with the same mass of oxygen at the same temperature. The ratio of the mean kinetic energies of hydrogen and oxygen is

A box contains n molecules of a gas. How will the pressure of the gas be effected, if the number of molecules is made $2n$

For a diatomic gas change in internal energy for unit change in temperature for constant volume is ${U_1}$ and ${U_2}$ respectively. ${U_1}:{U_2}$ is

Mean kinetic energy per degree of freedom of gas molecules is
