Abstract
By introducing new properties of state and an ideal system, that is, a perfect vapor, the representation of the thermodynamic properties of vapors is simplified. The field of state reduces to one curve of state which requires in the experimental investigation of vapors only as many measurements as are necessary for the determination of this curve. The equations of state are found more easily, the calculations required to determine the vapor tables are reduced, and a simple formula for the external work is found. An analytic investigation of the equilibrium of a liquid with its vapor shows how the vapor-pressure curve can be found from the equation of state.Keywords
