Which law governs the relationship between the pressure and volume of a fixed amount of gas at constant temperature?
Boyle's Law
Boyle's Law states that for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume.
This is expressed as \(P_1V_1 = P_2V_2\), meaning as volume decreases, pressure increases, and vice versa, while temperature and amount of gas remain unchanged.
Charles's Law relates volume and temperature at constant pressure, and Gay-Lussac's Law relates pressure and temperature at constant volume, so neither fits here.
Hence, the law governing pressure and volume at constant temperature is Boyle's Law.
