Question

If gas molecules undergo in elastic collision with the walls of the container, then (A) temperature of the gas will increase (B) temperature of the gas will fall (C) pressure of the gas will increase (D) neither the temperature nor the pressure will change

Tardigrade Admin · Accepted Answer

Usually, temperature of gas in a container is same as the temperature of the walls of the container. Therefore, during collision there is no exchange of energy. Hence, whether collision is elastic or inelastic molecules rebounce with average speed. Therefore, neither the temperature nor the pressure will change.

Q. If gas molecules undergo in elastic collision with the walls of the container, then

temperature of the gas will increase

temperature of the gas will fall

pressure of the gas will increase

neither the temperature nor the pressure will change
