MHT CET Physics question

The temperature of a gas in a rigid container is raised, the pressure exerted by the gas on the walls of the container increases because:

(A)the molecules lose more K.E. each time they strike the walls
(B)the molecules have higher average speed to strike the walls more oftenCorrect
(C)the molecules collides with each other more often
(D)the molecules lie in contact with the walls for small intervals

Answer: (B)

Solution

On heating, the average speed of the molecules increases, so they strike the walls more often and with greater momentum change per collision, raising the pressure; molecules do not lose more
