The ideal gas law, also called the general gas equation, is the equation of state of a hypothetical ideal gas. It shows the relation between the pressure P, volume V, and temperature T of gas in the limit of low pressures and high temperatures, such that the molecules of the gas move almost independently of each other. In such a case, all gases obey an equation of state known as the ideal gas law: PV = nRT, where n is the number of moles of the gas and R is the universal (or perfect) gas constant.

A law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature

Avogadro's Law is the relation that states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules.
