Q. A flask contains a monoatomic and a diatomic gas in the ratio of $4: 1$ by mass at a temperature of $300\, K$. The ratio of average kinetic energy per molecule of the two gases is

Kinetic Theory

Solution:

The average kinetic energy per molecule of any ideal gas is always equal to $\left(\frac{3}{2}\right) k_B T$. It depends only on the temperature and is independent of the mass and nature of the gas.
