Which principle applies when measuring the temperature and pressure of a gas simultaneously?

Boyle's Law
Charles' Law
Gay-Lussac's Law
Dalton's Law

The correct answer is: Gay-Lussac's Law

The principle that applies when measuring the temperature and pressure of a gas simultaneously is Gay-Lussac's Law. This law states that the pressure of a given mass of gas is directly proportional to its absolute temperature when the volume is held constant. This means that if the temperature of the gas increases, the pressure also increases, provided the volume does not change. This relationship highlights how temperature and pressure are interconnected in gas behavior. In contrast, Boyle's Law focuses on the relationship between the pressure and volume of a gas at constant temperature. It states that as the volume of a gas decreases, its pressure increases, provided the temperature remains constant. Charles' Law, on the other hand, describes how the volume of a gas relates to its temperature at constant pressure, illustrating that volume increases with temperature. Lastly, Dalton's Law deals with the behavior of mixtures of gases and the partial pressures of each component gas, rather than the direct relationship between temperature and pressure of a single gas.
