The laws and principles of thermodynamics govern the field of Mechanical Engineering. Whenever an engineer wants to design a motor or system they must take into account laws of energy, motion and friction that will effect how the machine works. Learn more about this field, including the basic laws and rules, and how to apply these rules to the development of machines and technologies.

What is Entropy? What is thermodynamic entropy?

The term entropy was first used by Rudolf Clausius to state the second law of thermodynamics. Though entropy is a simple term, many people find it difficult to understand its exact meaning. Let us see what is entropy, and its relation to second law of thermodynamics.

Applications of Second Law of Thermodynamics

The second law of thermodynamics is considered to be the most fundamental law of science. It explains not only the working of engines, refrigerators and other equipments used in our daily life, but also highly advanced theories like big bang, expansion of universe, heat death etc.
