Boyle’s Law states that

Boyle's Law states that the pressure of a gas is inversely proportional to its volume, assuming the temperature and amount of gas remain constant. This means that as the volume of a gas decreases, the pressure increases, and vice versa. The mathematical equation for Boyle's Law is P1V1 = P2V2, where P1 and V1 represent the initial pressure and volume, and P2 and V2 represent the final pressure and volume. To apply Boyle's Law, you need to know the initial and final pressure and volume of the gas. By rearranging the equation, you can solve for any of the variables.
