INVESTIGATION OF THE PROPERTIES OF SUBSTANCES ON THE BOUNDARY CURVES OF LIQUID-VAPOR PHASE TRANSITION
B. A. Arutyunov and A. B. Arutyunov UDC 536.24/25 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. M. V.
