A fixed mass of gas is enclosed in a cylinder fitted with a piston. The gas volume is gradually decreased while the temperature remains constant, and no gas particles leave the cylinder. Which statement is correct?
- AThe force exerted by the gas on the piston will decrease because the particles move more quickly.
- BThe force exerted by the gas on the piston will decrease because the particles move more slowly.
- CThe force exerted by the gas on the piston will increase because the particles are hitting the piston harder.
- DThe force exerted by the gas on the piston will increase because the particles are hitting the piston more frequently.
