The Second Law of Thermodynamics and Entropy
... Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specified conditions is that the photocopy or reproduction is not to be used for any purpose other than private study, scholarship, or research. If electron ...

Chapter 4 Entropy and second law of thermodynamics
... Let us consider now the processes involved. A → B: isothermic compression. Work is performed on the gas and an amount of heat Q1 < 0 is given to the reservoir in a reversible process. As a result, ∆S = QT1 diminishes. B → C: adiabatic expansion. The gas performs work. Since δQ = 0, the entropy remai ...
