Further discussion on “ΔSsys+ΔSsur ≥0 cannot determine the derection of a process”
Zeng Xiang · Journal of Guizhou University of Technology · 1999
As a change takes place,the practical process is always accompanied by a dispersal of energy in a more desordered form,from which the entropy change in the system can be calculated.ΔSsys+Ssur≥0 is proved to be true in any changes,spontanuous or compelled.Therefore,it does not ditermine the direction of change,but can only be a criterion for identifying reversible or irreversible process.
