Thermodynamics
The word thermodynamics is generated from two Greek words: Thermo and Dynamis
Thermo stands for heat and dynamis stands for power.

20. Thermodynamics
Objective
Thermodynamics plays a vital role in the analysis, development and design of all the
systems, considering such as increase in efficiency, improved and optimum design for
a dynamic and sustainable society.
Concerned with environmental issues related to all these devices.
We must consider how we can eliminate or at least minimize
damaging effects, as well as use our natural resources,
efficiently, and responsibly.
