A reaction vessel is fitted with a syringe. It contains gas at 1 atm and 18 °C. Calculate the pressure if the syringe is moved so that it is a quarter of its original volume. Assume temperature to be constant.

Question

Quizplus · Accepted Answer

According to Boyle's law, at constant temperature, the pressure and volume of a gas are inversely proportional. When the volume is reduced to a quarter of its original value, the pressure increases by a factor of 4. Therefore, the new pressure is 4 atm.
