A gas spring contains a fixed mass of gas. Its volume is reduced while its temperature remains constant. Which statement describes how the collisions of the gas particles with the walls of the gas spring change?
The particles reach the walls more often, but the force of each collision is unchanged.
The particles reach the walls less often, and the force of each collision is unchanged.
The particles reach the walls less often, but the force of each collision increases.
The particles reach the walls more often, and the force of each collision increases.
