Question

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

• 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 less frequency

Answer 1

Answer: (C)

Strike the wall more often with higher velocities

Answer 2

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.
