A sealed air cell in protective packaging contains a fixed mass of air. The cell is squeezed so that its volume decreases, while the temperature of the air stays the same. Which statement describes how the collisions of the air particles with the inside of the cell change?
They happen equally often, but each collision exerts a larger force than before.
They happen more often, and each collision exerts a larger force than before.
They happen more often, and each collision exerts the same force as before.
They happen less often, but each collision exerts the same force as before.
