If gas molecules undergo inelastic collision with the walls of container when temperature of gas is same as that of walls of container, then
(a) the temperature of the gas will decrease
the pressure of the gas will increase
( c) neither the temperature nor the pressure will change.
(d) the temperature of the gas will increase

Options

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

Answer

C

Explanation

When the temperature of the gas is the 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 or inelastic and consequently neither the temperature nor the pressure will change.
