Boyle's Law states that for a fixed amount of gas at a constant temperature, the pressure and volume are inversely proportional.

This means:

* As the pressure of a gas increases, its volume decreases.

* As the pressure of a gas decreases, its volume increases.

Mathematically, this is represented as:

P₁V₁ = P₂V₂

Where:

* P₁ is the initial pressure

* V₁ is the initial volume

* P₂ is the final pressure

* V₂ is the final volume

In essence, Boyle's Law tells us that if you squeeze a gas into a smaller space, the pressure will rise. Conversely, if you allow a gas to expand into a larger space, the pressure will fall.
