What is Amontons equation?

Amontons' equation describes the relationship between pressure and temperature in gases, formulated by French physicist Guillaume Amontons in the 17th century. It states that for a given mass of gas at constant volume, the pressure is directly proportional to its absolute temperature. Mathematically, it can be expressed as ( P \propto T ), where ( P ) is the pressure and ( T ) is the absolute temperature. This principle is foundational in thermodynamics and helps explain gas behavior under various conditions.
