Investigation of the Properties of Substances on the Boundary Curves of Liquid-Vapor Phase Transition

A new approach to construction of generalized dependences for different properties of substances is proposed. A study is made of the changes in the difference in the properties of various substances on the boundary curves of liquid-vapor phase transition. Generalization results obtained in processing of experimental data on the thermodynamic and transport properties of substances on the boundary curves of liquid-vapor transition of monatomic and multiatomic gases, normal and polar organic and inorganic liquids, alkali metals, and mercury are discussed. An analogous approach may be used in studying solid body-liquid and solid body-gas phase transitions. __________ Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 78, No. 4, pp. 37–42, July–August, 2005.
