Q. A flask contains hydrogen and helium gases in the ratio $1 : 3$ at temperature $300\, K$. The masses of helium and hydrogen molecule are in the ratio $2 : 1$. What will be the ratio of the average kinetic energies of these molecules at $600\, K$ ?

Kinetic Theory

Solution:

At equal temperature, the average kinetic energies are equal, therefore ratio is $1 :1$.
