Question

If gas molecules undergo inelastic collision with the wall of the container : (A) the temperature of the gas will decrease (B) the pressure of the gas will increase (C) neither the temperature nor the pressure will change (D) the temperature of the gas will increase

Tardigrade Admin · Accepted Answer

When the temperature of the gas is same as that of the walls of the container, there is no exchange of energy. Hence, the molecules will return with the same average speed, whether the collisions are elastic or inelastic and consequently neither the temperature nor the pressure will change.
