According to Gay-Lussac's Law, if the absolute temperature of a gas increases, what happens to the absolute pressure?

According to Gay-Lussac's Law, if the absolute temperature of a gas increases, the absolute pressure also increases, provided the volume of the gas remains constant. This relationship is expressed mathematically as ( P \propto T ), meaning pressure is directly proportional to temperature when measured in Kelvin.

When the temperature of a gas rises, the kinetic energy of the gas molecules increases, leading to more frequent and forceful collisions with the walls of the container. As a result, this increase in molecular activity generates a higher pressure.

This principle is crucial when working with gases in various applications, such as in HVAC systems where temperature changes can significantly affect pressure and the overall performance of the system. Understanding this relationship helps in predicting and managing the behavior of gases under varying thermal conditions.
