1st Law:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
2nd Law:
Clausius statement- It is impossible to convert heat from a lower-body temperature to higher body temperature without applying for the external work.
3rd Law:
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Zeroth Law:
It states that if two thermodynamic systems are each in thermal equilibrium with the third one then they are equilibrium with each other.
