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.
