According to Boyle's Law (P1V1 = P2V2), when the pressure on a gas increases, its volume decreases inversely if the temperature remains constant. In this case, the initial pressure (P1) is 100 kPa, and the initial volume (V1) is 100 liters. The final pressure (P2) is 400 kPa. To find the final volume (V2), we rearrange the equation to V2 = (P1V1)/P2 = (100 kPa * 100 liters) / 400 kPa = 25 liters.
