Question
Which gas law states that the pressure of a gas varies
directly with temperature when mass and volume remain constant?Solution
Gay-Lussac’s Law states that for a fixed mass and constant volume, the pressure of a gas is directly proportional to its absolute temperature. As temperature increases, gas molecules collide more vigorously, resulting in higher pressure.
