The temperature of a gas is raised while its volume remains constant, the pressure exerted by the gas on the walls of the container increases because its molecules

Options

A. lose more kinetic energy to the wall
B. are in contact with the wall for a shorter time
C. strike the wall more often with higher velocities
D. collide with each other with less frequency

Answer

C

Explanation

c. Due to increase in temperature root-mean-square velocity of gas molecules increases. So they strike the wall more often with higher velocity. Hence the pressure exerted by a gas on the walls of the container increases.
