Question

HELPPP PLEASE! What happens when you compress gas?

you increase its volume
you decrease its temp
you increase its density
you decrease the pressure

Answer 1

When a gas is compressed rapidly, temperature increases because temperature and volume of gas are inversely proportional to each other according to gas laws.

Answer 2

You increase its density.

Step-by-step explanation:

Think of what happens when you squeeze a balloon.

A is wrong, because the volume decreases. The balloon gets smaller.

B is wrong. The temperature of the balloon does not change.

C is correct. You increase the density of the gas. Density = mass/volume. You have the same mass of gas in a smaller volume, so its density increases.

D is wrong. The more you compress the balloon, the more difficult it becomes. The pressure increases.
