【Abstract】 This paper mainly relies on the basic principles of thermodynamics in physical chemistry, has a shallow discussion of thermodynamic methods and a brief introduction of chemical thermodynamic methods and engineering thermodynamic methods. Thermodynamic methods mainly include cycle method, characteristic function method, variable transformation method, standard state method, equilibrium method, extreme value method, micro-element method, etc., and the characteristics, functions and significance of various methods are summarized. It has a certain guiding significance for students to learn the thermodynamics in physical chemistry, and expands the basic knowledge of thermodynamics.更多还原
