Answer:

The density increases.

Explanation:

We know that density, #rho#, is denoted by #rho=m/V#.

Since, according to Boyle's Law, #Pprop1/V#, as pressure increases, volume decreases.

We also know that #rhoprop1/V#, or #Vprop1/rho#.

By the above, we can say that when volume decreases, density increases.

Therefore, when a gas is compressed its density increases.
