Question

Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will ___________

(a) Increase

(b) Decrease

(c) Remain the same

(d) Decreases for some, while the increase for others

I got this question in homework.

I need to ask this question from Kinetic Theory of Gases in section Kinetic Theory of Gases of Engineering Physics I

Answer 1

The correct answer is (c) Remain the same

Explanation: The centre of mass of the gas molecules moves with uniform speed along with the lorry. As there is no change in relative motion, the translational kinetic energy and hence the temperature of the gas molecules will remain the same.
