Average kinetic energy of molecules is

The specific heat of a gas

Latent heat of ice is

For a gas, the r.m.s. speed at 800K is

A room temperature the r.m.s. velocity of the molecules of a certain diatomic gas is found to be 1930 m/sec. the gas is\

According to kinetic theory of gases, at absolute zero of temperature

One mole of an ideal gas requires 207 J heat to raise the temperature by 10 K, when heated at constant pressure. If the same gas is heated at constant volume to raise the temperature by 10K, then heat required is
