, , and He are enclosed in identical containers under the similar conditions of pressure and temperature. The gases will have

(A)Same R.M.S. speed
(B)Same
(C)Different
(D)Same Correct

Answer: (D)

Solution

At the same P, T and volume the gases contain equal numbers of molecules with equal average kinetic energy, so K.E. per unit volume is
