Question 68

A gas is trapped in a cylinder by a piston. The volume of the gas is 150 cm3 and the pressure of the gas is PPP.

The piston is pulled slowly to the right so that the volume of the gas is increased to 300 cm3. The temperature of the gas does not change.

What is the new pressure of the trapped gas?

A

P2\frac{P}{2}2P​

B

PPP

C

2P2P2P

D
