When is Gay-Lussac's Law applicable?

Gay-Lussac's Law describes the relationship between the pressure and temperature of a gas when the volume and the amount of gas are held constant. According to the law, as the temperature of a gas increases, so does its pressure, provided no gas can escape and the volume does not change. This relationship is mathematically expressed as ( P/T = k ), where ( P ) is the pressure, ( T ) is the temperature in Kelvin, and ( k ) is a constant.

It's important to note that this law specifically applies when the volume is fixed; if the volume were to change, the pressure-temperature relationship would no longer hold in the same manner, as volume changes introduce additional variables into the equation. Understanding this relationship is crucial for handling gas laws, especially in closed systems where the containment provides a constant volume environment.
