Question

The mean kinetic energy of one mole of gas per degree of freedom (on the basis of a kinetic theory of gases) is ___________

(a) (1/2) kT

(b) (3/2) kT

(c) (3/2) RT

(d) (1/2) RT

This question was addressed to me in exam.

Question is from Gases in section Kinetic Theory of Gases of Engineering Physics I

Answer 1

Correct option is (d) (1/2) RT

For explanation: Mean kinetic energy per mole pf a gas per degree of freedom = (1/2) RT.
