Combined Gas Law

The combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.

The combined gas law shows that the product of the initial pressure and volume divided by the intial temperature equals the product of the final pressure and volume divided by the final temperature.

Formula

(QuantityVariable[Subscript["P", "1"], "Pressure"]*QuantityVariable[Subscript["V", "1"], "Volume"])/QuantityVariable[Subscript["T", "1"], "Temperature"] == (QuantityVariable[Subscript["P", "2"], "Pressure"]*QuantityVariable[Subscript["V", "2"], "Volume"])/QuantityVariable[Subscript["T", "2"], "Temperature"]
