Learn Thermodynamics with Free Lessons & Tips

There are four laws of thermodynamics :-

1) First law of thermodynamics:- It states that energy can neither be created nor be destroyed, but it can be changed from one form to another.

2) Second law of thermodynamics:- It states that the entropy in an isolated system always increases.

3) Third law of thermodynamics:- It states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

4) Zeroth law of thermodynamics:- It states that if two bodies are individually in equilibrium with a separate third body, then the first two bodies are also in thermal equilibrium with each other.

In the Graduate Aptitude Test in Engineering (GATE), thermodynamics is an important subject, especially for candidates in mechanical, chemical, and aerospace engineering. Here are some key topics that are often emphasized:-

Laws of thermodynamics, thermodynamics cycles, properties of pure substances, heat transfer, thermodynamics relationship, combustion, AC and refrigerator etc.
