MHT CET 2025 Physics question

For a gas at a particular temperature on an average, the quantity which remains same for all molecules is

(A)velocity
(B)momentum
(C)kinetic energyCorrect
(D)angular momentum

Answer: (C)

Solution

In kinetic theory the average translational kinetic energy of a molecule is , which depends only on the absolute temperature and is independent of the mass or nature of the gas. So at a given temperature the average kinetic energy is the same for the molecules
