In this post, we will see the book Thermodynamics by I. P. Bazarov.

# About the book

This book is the first part of a course on “Thermodynamics and Statistical Physics” held at present in physical and physico-mathematical faculties of our universities. In comparison with existing courses of thermodynamics the book has the following distinctive features:

1. Greater attention than in other books is devoted to a discussion of the initial propositions of thermodynamics, which enables us to establish both the limitations of thermodynamics and its organic connexion with statistical physics.

2. The content of the second law of thermodynamics is analysed

logically and with greater consistency, by taking into account the existence of negative absolute temperatures.3. The methods of thermodynamics are considered and discussed in detail.

4. The theory of critical phenomena is expounded according to

Gibbs, which enables us to establish the connexion of these phenomena with phase transitions of the second kind.5. The thermodynamics of systems with negative absolute temperatures is treated.

6. The fundamentals of the thermodynamics of irreversible processes are given.

7. The large number of problems included in the book form an integral part of the course. Many are devoted to certain additional questions that are not always treated in the course and do not enter in the main text of the book. For these reasons the solutions of the problems are set out in as much detail as possible.

The book was translated from Russian by F. Immirzi and translation edited by A.E.J. Hayes. The book was published in 1964.
