Robert Boyle (1627-1691) English physicist and chemist, first determined that compressibility of air in a closed system varied with pressure in a simple inverse relationship. If pressure doubled, volume halved. The first and second states of a closed system's pressure and volume can be stated as
P1V1 = P2V2
Otherwise known as Boyle's Law. In 1662, he performed the experiment to esatblish this principle by trapping air in the closed end of a tube shaped like a J, and added a known quantity of mercury ot increase the pressure, and noted the change in the volume.
