Gay-Lussac's Law expresses

Gay-Lussac's law describes how, at a fixed volume and with the amount of gas constant, pressure is directly proportional to absolute temperature. As temperature rises, gas molecules move faster and collide with container walls more forcefully and more often, increasing pressure. Because this relationship uses absolute temperature, temperatures should be in Kelvin for the proportionality to hold. The correct expression is P1/T1 = P2/T2, which means pressure divided by temperature remains the same when volume and moles don't change. If the pressure increases, the temperature must increase proportionally (in Kelvin). The other forms don’t fit this scenario: keeping pressure the same while changing temperature would violate the law; keeping temperature the same would imply no change in pressure; and multiplying pressure by temperature (P1×T1 = P2×T2) does not reflect the direct P ∝ T relationship at constant volume.
