Question 9

A fixed mass of gas at a constant temperature is trapped in a cylinder which has a movable piston.

Which row states and explains what happens to the pressure of the gas in the cylinder when the volume of the gas is decreased?

A

Pressure: decreases | Explanation: gas particles collide with the cylinder less frequently

B

Pressure: decreases | Explanation: gas particles collide with the cylinder at a lower speed

C

Pressure: increases | Explanation: gas particles collide with the cylinder at a higher speed

D

Pressure: increases | Explanation: gas particles collide with the cylinder more frequently
