According to Boyle's Law, if the volume of a gas decreases, what happens to its pressure?

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature and the number of gas molecules remain constant. This relationship can be expressed mathematically as P1V1 = P2V2, where P is the pressure and V is the volume.

When the volume of a gas decreases, the molecules are forced closer together. As a result, they collide with the walls of their container more frequently and with greater force, which leads to an increase in pressure. Therefore, if the volume of a gas decreases, its pressure must increase in order to maintain the equilibrium described by Boyle's Law.
