360208 The pressure of a gas does not depend up on

1 Kinetic energy of its molecules
2 The temperature of gas
3 The density of the gas
4 The volume of the gas when the density remains unchanged
PHXI13:KINETIC THEORY

360209 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.

1 Lose more kinetic energy to the wall
2 Are in contact with thewall for a shorter time
3 Strike the wall more often with higher velocities
4 Collide with each other with less frequency.
