Question 85

A piston traps a fixed mass of gas inside a cylinder. The piston is pushed into the cylinder, reducing the volume occupied by the gas. The temperature of the gas is kept constant.

How are the density and the pressure of the gas affected by this change?

A

Density increases; pressure remains unchanged

B

Density increases; pressure increases

C

Density decreases; pressure decreases

D

Density decreases; pressure increases
