# How is Boyle's law written mathematically?

May 12, 2014

Boyle's Law is a relationship between pressure and volume.

${P}_{1} {V}_{1} = {P}_{2} {V}_{2}$

In this relationship, pressure and volume have an inverse relationship when temperature is held constant. If there is a decrease in the volume there is less space for molecules to move and therefore they collide more often, increasing the pressure. If there is an increase in the volume the molecules have more space to move, collisions happen less often and the pressure is decreased.

vV ^P ^V vP the relationship is inverse.
