Introduction to thermodynamics

This book is aimed for freshman undergraduate students who study at Tecnológico de Monterrey, Campus Quer ́etaro, M ́exico, who are studying for first time thermodynamics. In this book is covered the basics of thermodynamics and we mention some applications of thermodynamics. These lecture notes introduce as smoothly as possible mathematical formalism. All the material is self contained, just basic dynamics and kinematics is assumed. Also, basic integral and differential calculus is assumed. At the same time, it is assumed that the reader is confident with conversion of units. We will focus in understanding the physics, in presenting different practice exercises, and the nature of thermodynamics in different situations, rather than a highly formal and mathematical description.
