New Universal Relations for Liquid-Vapor Phase Equilibrium

Universal relations between the saturation pressure pLV and the value of .=2hLV 2&LV&pLV , where 2hLV is the latent heat of evaporation and 2&LV is the volume change of the vapor-liquid transition, and the product of the orthobaric densities \L and \V of the liquid and vapor at coexistence have been discovered. In the temperature range from the triple point to T Tcr0.9, these relations obey a power law with universal exponents. At temperatures 0.9
