Explain Thermodynamic laws

Explain Thermodynamic laws and also First law, Second law, third law and zeroth law of thermodynamics?

Thermodynamic laws:

First law of thermodynamics: The change in an internal energy of a system is the addition of the heat transferred to or from the system and the work-done on or by the system.

Second law of thermodynamics: The entropy is a measure of the unavailability of the system's energy to do helpful work-of a closed system tends to raise with time.

Third law of thermodynamics: For changes including only perfect crystalline solids at absolute zero, the modifications of the net entropy is zero (0).

Zeroth law of thermodynamics: When two bodies are each in thermal balance with a third body, then all the three bodies are in thermal equilibrium with one other.
