# How can Boyle's law be represented?

Jul 2, 2017

See below

#### Explanation:

Boyle's law states that the volume occupied by a gas and the pressure the gas exerts are inversely proportional:

$P \propto \frac{1}{V}$

or

$V \propto \frac{1}{P}$

Under constant temperature (and quantity of gas), these two variables are represented by the equation

color(blue)(P_1V_1 = P_2V_2

You can use this formula to solve problems that deal with pressure and volume gas relationships.

For example, if you were given an initial pressure and volume, and the volume changed by a certain amount, you'd use this equation to calculate the final pressure, or vice versa.
