## Boyle's law

A law of gases which states that at constant temperature the volume of a gas varies inversely with its pressure. This law, formulated by Robert Boyle (1627–1691), can also be stated thus: The product of the volume of a gas times the pressure exerted on it is a constant at a fixed temperature. The relation is approximately true for most gases, but is not followed at high pressure. The phenomenon was discovered independently by Edme Mariotte about 1650 and is known in Europe as Mariotte's law. See Kinetic theory of matter

By his ingenious investigations, it was given to our countryman Van der Waals to shed the full light of theory on the deviations from Boyle's law and on the continuity of the gaseous and the liquid state, and to explain this from the motion of molecules.
Another student at Sunapee Middle High School in New Hampshire used digital photographs and a PowerPoint slide presentation to document a physics lab on Boyle's Law, which proves that an increase in gas pressure decreases the volume, and vice versa.

Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure; therefore, if the pressure of gas doubles, its volume is compressed in half.
Most students used stuff like Boyle's Law (gas cools off when it expands and heats up when it is compressed).
Boyle's law is an empirical law - an observed regularity.
In chemistry, they should be learning Boyle's law by puffing some air into their mouths (gas in a chamber) and then seeing the pressure go up when they put all the air into one side, where it occupies a smaller volume (Boyle's law: volume is inversely proportional to pressure).
