To develop your creativity and understanding of the ideas, we have included a number of problems at the end of each lecture. This is followed by worked examples drawn from everyday life to help clarify the principles and indicate possible applications. Lastly, Lecture 6 deals with phase changes and phase equilibrium in thermodynamic systems.Įach lecture begins with clear statement of study objectives, pertinent definitions and simple qualitative explanations of principles together with illustrations.

Lecture 5 introduces thermodynamic potentials and Maxwell/s equations. Lecture 4 deals with Entropy and the concept of reversibility. Lecture 3 deals with the 2ND Law of thermodynamics which gives the direction of natural thermodynamic processes and defines the thermal efficiency of devices that convert heat into work and vice versa. Lecture 2 deals with the 1ST Law of thermodynamics which introduces the concept of internal energy. Lecture 1 begins by defining basic thermodynamic concepts and the Zeroth law which introduces the concept of thermal equilibrium and temperature. This module attempts to provide a clear and modern view of the essential Principles of Thermodynamics and its applications, relevant to Science and Engineering.

These relationships are governed by the four laws of thermodynamics which are now some of the most important fundamental laws in nature. Thermodynamics is the study of relationships involving heat, mechanical work and other aspects of energy transfer that takes place in devices such as refrigerators, heat pumps, internal combustion engines etc. Today the scope of thermodynamics has immensely increased with innumerable applications in chemistry and engineering. The study of thermodynamics was inaugurated by 19th -century engineers, who wanted to know the ultimate limitations the laws of physics impose on the operation of steam engines and other devices that convert heat to mechanical energy and vice versa.
