# Boyle's Law

**Formula:** `P1 × V1 = P2 × V2`

Where ** P1** is the initial pressure,

**is the initial volume,**

*V1***is the final pressure, and**

*P2***is the final volume.**

*V2*Boyle's Law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume when the temperature remains constant within a closed system. Mathematically, this is expressed as P1 × V1 = P2 × V2. This law is derived from kinetic theory and assumes ideal gas behavior. It's commonly used to predict the behavior of gases under pressure changes and is important for various scientific and engineering applications, including scuba diving, gas syringe experiments, and designing pneumatic systems.
