Fundamentals of Engineering Thermodynamics


Thermodynamics is a basic science that deals with energy. In other words, thermodynamics may be defined as the study of energy, its forms and transformations, and its interaction with matter. Thermodynamics also deals with various properties of substances and the changes in these properties as a result of energy transformations. The principles of thermodynamics are based on our day-to-day experiences and experimental observations.

The name thermodynamics stems from the Greek words therme (heat) and dunamis (power), which terms in early days were used to describe the effort to convert heat into power. But in the present context, the name thermodynamics is used to interpret all aspects of energy and energy transformations, including power production, refrigeration, and relationships among the properties of matter.

It has been said that thermodynamics may be defined as the science of energy. Even though it is easy to feel the energy, it is difficult to give a precise definition to it. Energy may be viewed as the capacity to do work or the ability to cause changes. One of the most fundamental laws of nature is the law of conservation of energy. It simply states that during an interaction, energy can
change from one form to another but its total amount remains constant. That is, energy is neither created nor destroyed; it can only change forms (r€ First Law of Thermodynamics).
