Twenty Lectures on Thermodynamics is a course of lectures, parts of which the author has given various times over the last few years. The book gives the readers a bird''s eye view of phenomenological and statistical thermodynamics. The book covers many areas in thermodynamics such as states and transition; adiabatic isolation; irreversibility; the first, second, third and Zeroth laws of thermodynamics; entropy and entropy law; the idea of the application of thermodynamics; pseudo-states; the quantum-static al canonical and grand canonical ensembles; and semi-classical gaseous systems. The text is recommended for physics students who are in need of a basic yet effective knowledge in the foundations of thermodynamics, as the book explains its many concepts in such an elementary and pedagogic manner, giving the readers a greater understanding of the core of the subject.
