Boyle's Law states that the volume of a gas is inversely proportional to its pressure, assuming constant temperature. This means that if the volume of a gas increases, the pressure will decrease, and vice versa.

Here's the mathematical representation of Boyle's Law:

P₁V₁ = P₂V₂

Where:

* P₁ = Initial pressure

* V₁ = Initial volume

* P₂ = Final pressure

* V₂ = Final volume
