Question

What happens when you compress a gas?

Question 26 options:


The temperature decreases


The density increases


The volume increases


The pressure decreases


Depends on the gas

Answer 1

Density increases

Step-by-step explanation:

Just took test

Answer 2

The density increases.
When gases are compressed, their volume decreases, and the resulting pressure increases. The temperature will change if either P or V are held constant. Since the volume decreases, then density, or m/V, increases.
P×V ~ T
