The gas in the piston is at constant temperature. A student increases the pressure on the piston from 2 atm to 3 atm. Open image in full-screen view Which gas law would a student use to investigate this situation?

Because the gas stays at a constant temperature, the pressure–volume relationship is described by Boyle’s law. Boyle’s law says that pressure and volume change inversely, so increasing pressure from 2 atm to 3 atm would decrease the gas’s volume. The correct choice is Boyle’s law.
