Question

Mean kinetic energy per degree of freedom of gas molecule is

Answer 1

According to kinetic theory of gases, the mean kinetic energy of a molecule is 3/2 kT. Since molecules move at random, the average kinetic energy correspoonding to each degree of freedom is the same. Thus, mean kinetic energy per molecule per degree of freedom is ½ kT.

According to kinetic theory of gases, the mean kinetic energy of a molecule is 3/2 kT. Since molecules move at random, the average kinetic energy correspoonding to each degree of freedom is the same. Thus, mean kinetic energy per molecule per degree of freedom is ½ kT.
