This work has been written as support for Physical Chemistry courses taught in the areas of Chemistry and Chemical Engineering, and for this purpose it presents the fundamental concepts and basic calculation techniques of Thermodynamics, Thermophysics and Thermochemistry.

In order to make this book as didactic a tool as possible, the selection of the problems included and the detailed solution presented for each of them were elaborated based on the experience acquired by both authors in teaching this subject.

In addition to being solved in detail all the problems presented, at the beginning of each chapter the corresponding basic theory is exposed.

Learn: to apply the fundamental theory of Physicochemistry in the solution of specific problems of this matter.
Know: the most important solution techniques of the problems of Physicochemistry.
