A gas contained in a piston has a pressure of 100. torr and a volume of 1.0 L. Determine the pressure of the gas if it is compressed to a volume of 0.75 L at the same temperature .

Question

Quizplus · Accepted Answer

Boyle's law states that the pressure of a gas is inversely proportional to its volume at constant temperature. Therefore, if the volume of a gas is decreased, its pressure will increase. In this case, the volume of the gas is decreased from 1.0 L to 0.75 L, so the pressure of the gas will increase by a factor of 1.0 L / 0.75 L = 1.33. Therefore, the new pressure of the gas will be 100. torr * 1.33 = 133 torr.
