Thermodynamics

What is thermodynamics?

Thermodynamics is one of the types of physics which is the combination of two words ” thermal + heat”, thermal means heat, and dynamic means motion. So literally thermodynamic means study of the motion of heat. There are three laws of thermodynamics which are:

Thermodynamic plays a vital role in our lives.
Think!
Without TD…..

We were not able to get the energy to move. We get energy from food as a result of the metabolism process which is the example or application of the first law of TD.
Refrigerators, air conditioners, cars, airplanes, buses, ships all needed a thermodynamic system to work.
Heat pumps and heating systems are due to TD.
Electricity is now being produced by using a thermodynamic cycle or process.

It is applicable only in the macroscopic world and not in the microscopic.
