Explanation

According to Boyle's Law, for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume

. This means that if you decrease the volume, the pressure will increase, and vice versa.

Mathematically, it is expressed as: P1V1 =P 2​ V2  where  P is the pressure, and V is the volume.

Therefore, if the volume decreases, the pressure will increase.
