Ideal Gas State Equation was first stated by Benoît Paul Émile Clapeyron in 1834. It determines the relationship between its pressure, volume and temperature.

The Equation of State of an Ideal Gas, which is a good approximation to real gases at sufficiently high temperatures and low pressures; that is, PV = RT where P is the pressure, V is the volume per mole of gas, T is the temperature, and R is the gas constant.

Any equation that relates the Pressure, Temperature, and Specific Volume of a substance is called the equation of state.
