Abstract:
Thermodynamic analysis is performed of the behavior of a number of thermodynamic characteristics of single-component substance under conditions of hypothetical continuous liquid—vapor phase transition. It is demonstrated that the internal energy and enthalpy in passing the spinodal exhibit on isotherms no special features depending on volume; and the isochoric heat capacity on the entire thermodynamic surface, including the metastable region of states and the region defined by the spinodal, remains positive and finite except for the critical point.
