# What are the properties of Boyle's law?

Mar 30, 2018

The pressure is inversely proportional to the volume of a gas.

#### Explanation:

Boyle's law states that, At a constant temperature and the number of moles of a gas, the pressure is inversely proportional to the volume of a gas.

In equation form, this is written as $P \propto V$ or ${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$.

Here is a picture about the law:

Boyle's law states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles are constant.

#### Explanation:

${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$
${P}_{1}$ and ${V}_{1}$ represent the pressure and volume of a gas before a change occurs.
${P}_{2}$ and ${V}_{2}$ represent the pressure and volume of a gas after a change occurs.
