Explain the Laws of Thermodynamics

Usually thermodynamics contains four laws;

a. Zeroth law:  this law deals with thermal equilibrium and establishes an idea of temperature.

b. The First law: this law throws light on concept of internal energy.

c. The Second law: points out the limit of converting heat into work and introduces the principle of increase of entropy.

d. Third law: describes the absolute zero of entropy.
