Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is constant. This relationship can be expressed mathematically as:
P1V1=P2V2P_1 V_1 = P_2 V_2P1?V1?=P2?V2?
Where:
P1P_1P1? and V1V_1V1? are the initial pressure and volume.
P2P_2P2? and V2V_2V2? are the final pressure and volume.
