A

Pressure increases because gas particles collide with the cylinder walls more frequently

B

Pressure increases because gas particles collide with the cylinder walls less frequently

C

Pressure decreases because gas particles collide with the cylinder walls more frequently

D

Pressure decreases because gas particles collide with the cylinder walls less frequently
