WebbThis expression can be obtained from the pressure-volume relationship suggested by Boyle’s law. For a fixed amount of gas kept at a constant temperature, PV = k. Therefore, P1V1 = k (initial pressure * initial volume) P2V2 = k (final pressure * final volume) ∴ P1V1 = P2V2. This equation can be used to predict the increase in the pressure ...
