The only monograph in the world literature specifically devoted to the differential equations of thermodynamics. The book comprehensively sets out the issues of using the apparatus of differential equations for the analysis of thermodynamic systems. Characteristic functions, differential equations for a single-phase region, discontinuities of thermodynamic functions on boundary curves, equations for a two-phase region, features of the mathematical description of the critical point, equations for complex thermodynamic systems are considered in detail. Characteristic errors made in calculations using differential equations of thermodynamics are analyzed. Intended for specialists in the field of thermophysics, graduate and senior students of thermophysical, engineering physics, physics and technology universities and faculties.
