# What do Boyle's law and Charles's law have in common? How are they different?

Nov 5, 2016

They are both gas laws that relate to the volume of a gas.
Boyles law is an inverse relationship Charles law is a direct relationship. /

#### Explanation:

Boyle's law says that volume changes inversely with pressure

$P = \frac{1}{V}$ or ${P}_{1} \times {V}_{1} = {P}_{2} \times {V}_{2}$

Charles law says that volume changes directly with absolute temperature

${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$ or ${V}_{1} \times {T}_{2} = {V}_{2} \times {T}_{1}$

Both laws describe how the volume of a gas changes.

Boyles law states that as the pressure increases the volume decreases.

Charles law states that as the the absolute temperature increases the volume increases
