Heat is basic science that deals with energy and has long been an essential part of Engineering Curricula all over the world. It was developed during the eighteenth and nineteenth century during a time when Temperature and Heat were not well understood yet. Its development was driven by the need for an improved theoretical understanding of Steam Engines invented at the same time. It evolved as a rather formal and elegant theory that proved to be of great importance to Engineers. Thermodynamics is the science of Energy, Heat, Work, Entropy and Spontaneity of processes. It is closely related to Statistical Mechanics from which many

Thermodynamic relationships can be derived. While dealing with processes in which systems exchange Matter or Energy, Classical Thermodynamics is not concerned with the rate at which such processes take place, termed Kinetics. The book contains detailed descriptions of Modern Techniques in Thermodynamics. The aim of the book is to make the subject matter broadly accessible to advanced students, whilst at the same time providing a reference text for graduate scholars and research scientists active in the field.
