CRC release: The aim of this book is to provide an in-depth view of the subject with all its mathematical complexity while keeping the focus practical. The book covers the subject in an innovative way, from the first principles of thermodynamics to applied topics of interest for practicing engineers and researchers. From the first chapters it takes out the myth of the mysterious nature of entropy and the remoteness of the Gibbs, Helmholtz and other functions, integrating them to the representation of physical phenomena. It provides a concise description of the fundamental concepts and uses real-world examples to show how to solve practical problems.
