Second Law of Thermodynamics

It is specific to the second law of thermodynamics, It is divided into a group of elements, the first of which is the contents, then spontaneous processes, followed by the causes of spontaneity in the first pages, then begins with the definition of entropy and introversion, then the paragraph of the second law, followed by the chapters of the third law, And the input units and the entry criterion, then the standard entry of formation and the derivation of convergence from the Kano cycle, followed by the introduction of change in an irreversible process, and it begins with an explanation of the physical importance of engagement, then the introduction of the change that accompanies the change of stage, then the Gibbs-Helmholtz equations, then the Chaperon equations, then the Clausius-Clapeyron equations and their applications, then Followed by the free energy and work functions, then Hovisocor, then displacement, activity and physical capabilities, followed by the Jeeps Rahm equation, then the Dimas arrow, The guide ends with an explanation of the zero law of thermodynamics, multiple-choice questions, and a general review, It is suitable for the middle and third stage for the age group from 14 to 20 years.
