A sample of a gas is held at constant temperature.If the number of moles of gas in the sample is doubled while the pressure is halved,what will happen to the volume of the gas sample?

Question

Quizplus · Accepted Answer

According to the combined gas law, at constant temperature and number of moles, the pressure and volume of a gas are inversely proportional. Therefore, if the pressure is halved, the volume must double to maintain a constant value of the product of pressure and volume. Hence, the volume of the gas sample will increase.
