The gas in the piston is at constant temperature. A student increases the pressure on the piston from 2 atm to 3 atm.
A container has a piston pushing down on it. A down arrow above the container is labeled P equals 2 atmospheres.

Which gas law would a student use to investigate this situation?
Boyle’s law
Charles’s law
Gay-Lussac’s law
ideal gas law

Boyle’s law.

Reason: Boyle’s law (P1V1 = P2V2) describes the inverse relationship between pressure and volume at constant temperature. Charles’s and Gay-Lussac’s laws involve temperature changes; the ideal gas law is more general but not needed when T is constant.
