Boyle's Law is a basic principle in gas physics that states that at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure.

Charles' Law: This law states that volume and temperature are directly proportional to each other as long as pressure remains constant.
The equation PV=nRT where P is the pressure, V is the volume, n is number of moles, R is universal gas constant and T is temperature; combines Boyle’s law, Charles’ law and Avogadro’s law.
