The ratio of average translatory kinetic energy of He gas molecules to O 2 gas molecules is

Question

The ratio of average translatory kinetic energy of He gas molecules to O 2 gas molecules is (A) (25/21) (B) (21/25) (C) (3/2) (D) 1

Tardigrade Admin · Accepted Answer

Both He and O 2 have 3 translatory degrees of freedom. At the same temperature, energy is divided equally in all degrees of freedom. Hence ratio of the translatory kinetic energy is one.

Q. The ratio of average translatory kinetic energy of $He$ gas molecules to $O_{2}$ gas molecules is
