There are laws of thermodynamics
1. Zeroth law
2. First law of thermodynamics
3. Second law of thermodynamics
4. Third law of thermodynamics

Zeroth laws says that energy can neither create nor be destroyed. It can be transform from one form into another.

First laws (laws of conservation of mass) one form of energy is convert into another form.

Second laws states that law in physics: mechanical work can be derived from the heat in a body only when the body is able to communicate with another at a lower temperature or all actual spontaneous processes result in an increase of total entropy.

Third law states that at the absolute zero of temperature the entropy of any pure crystalline substance is zero and its derivative with respect to temperature is zero.
