The pressure to volume relationship is an inverse proportion. This means as pressure increases volume decreases and as pressure decreases the volume would increase. The temperature must remain constant.

Boyle’s Law can written as K=PV. The most common form of Boyle’s Law used is P1V1=P2V2
Example Problem:
A balloon at 3 atm expands from 20 mL to 30 mL, what is the new pressure?
P1= 3 atm
P2= ?
V1= 20 mL
V2= 30 mL
You take Boyle’s Law P1V1=P2V2 and rearrange the variables to fit the new formula for the variable that needs to be solved.
P2= P1V1/V2
P2= 3 atm(20 mL)/30 mL
P2= 2atm
