two gases hydrogen and oxygen are in thermal equilibrium . then what is the ratio of kinetic energies of hydrogen and oxygen molecules

Open in App

Solution

The average kinetic energy of any ideal gas is always equal to (3/2) k_BT where k_Bis Boltzmann constant. It depends only on the temperature and is independent of the nature of the gas.
Since Oxygen and hydrogen both have the same temperature due to thermal equilibrium, so the ration of average kinetic energy of the two gases is 1:1.
