BOYLE'S LAW

branch THERMAL PHYSICS

Coming from GASES
Leading to THE IDEAL GAS LAW

Boyle's law is an experimental gas law which describes how the pressure of a gas tends to decrease as the volume of a gas increases. A modern statement of Boyle's law is


The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.


Mathematically, Boyle's law can be stated as:


P1V

or


PV=k

where P is the pressure of the gas, V is the volume of the gas, and k is a constant.
