Answer 1

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

Explanation:

The centre of mass of gas molecules moves in lockstep with the vehicle. Because the gas molecule has no relative motion. As a result, kinetic energy and thus temperature remain constant.
