Abstract To solve the problem that the students are difficult to remember and master the calculation formulas of entropy difference in the chemical thermodynamics, this paper presents a method which can strengthen the memory of the formulas through the interactive verification of the calculation formulas. Firstly, the paper introduces the conventional deductive method which is based on the entropy definition. Then, the paper introduces another differential deductive method based on the thermodynamic basic equation and the whole differential, and verifies interactively the results of the entropy difference calculation obtained by these two deductive methods. In addition, the equation of adiabatic process of the ideal gas and the corresponding formulas of entropy difference calculation are also deduced.
