| Abstract: | In this paper, the method to calculate the enthropy change was illustrated, and the application of Clausius unequal relation was discussed. Moreover, the application of enthropy criterion to judge the possibility of the thermodynamic process occurring was studied qualitatively and quantitatively, and the problem of to judge the occurrence possibility of the reversible process or irreversible process by enthropy criterion was resolved completely. |
