Which gas law describes how gas volume changes with pressure for a fixed amount of gas at constant temperature?

Explanation:
The main concept is that, for a fixed amount of gas at constant temperature, pressure and volume are inversely related. This is Boyle's Law: the product of pressure and volume stays constant (PV = constant). So, if you increase the pressure by compressing the gas, its volume must decrease proportionally to keep PV the same; doubling the pressure would roughly halve the volume for an ideal gas. This contrasts with other gas laws: Charles's Law describes how volume changes with temperature at constant pressure, Avogadro's Law ties volume to the amount of gas at fixed T and P, and Henry's Law deals with how gases dissolve in liquids under pressure.
