Boyle's law The relationship between the volume and pressure of a gas was studied experimentally by Robert Boyle in 1662. He used mercury and a simple U-tube. The pressure was increased by putting more mercury into the open limb. The volume of the air enclosed in the space above mercury in the shorter limb was noted each time. Boyle's law states that … [Read more...] about Gas Laws
