The discussion of entropy and reversibiliy concepts

This study was carried out to enlighten the most complicated concepts of thermodynamics entropy and reversibility. For this purpose the subject was thoroughly investigated from the physical chemistry text books and the subject of entropy as the parameter of which determines the instantaneous events and the state function property was thoroughly discussed. This study is different than most of the conventional education thesis in many respects. There is no pretest post test pattern was employed and there was no attempt to bring any statistical explanation. This study is expected to enlighten these complicated and mostly misunderstood concepts. Keywords: Entrophy, reversibility and the second law of thermodynamics
