**Boyle's Law is a gas law that describes the relationship between the pressure and volume within a closed system when temperature is constant.**

The law is named after chemist and physicist, Robert Boyle who published the original law in 1662.

A definition of Boyle's Law states:

For a fixed amount of gas kept at a fixed temperature, P and V are inversely proportional (while one increases, the other decreases)

The equation for Boyle's Law is as follows:

PV = k

P denotes the pressure of the system.

V is the volume of the gas.

k is a constant value representative of the pressure and volume of the system.
