Gay Lussac's Law can be expressed in which equation format?

Gay Lussac's Law articulates the relationship between the pressure and temperature of a gas when the volume is kept constant. This law states that the pressure of a gas is directly proportional to its absolute temperature (measured in Kelvin) when the amount of gas and the volume does not change. The correct mathematical representation of this relationship is given by the equation P/T = k, where P is the pressure, T is the absolute temperature, and k is a constant.

In this context, as the temperature increases, the kinetic energy of the gas molecules increases, leading to an increase in pressure. Conversely, if the temperature decreases, the pressure likewise diminishes. This fundamental relationship is critical in understanding gas behavior and is utilized in various applications across respiratory care, physics, and other scientific fields.
