First Law

Law of Conservation of Energy or the first law of thermodynamics states that there is no creation or destruction of energy, but it can only be changed or transferred from one form to another.

The Second Law of Thermodynamics

Here in this law, it states that there is a rise in the isolated system’s entropy. It is because the systems evolve towards thermal equilibrium. It is the state where the system has maximum entropy. It means that there is a rise in the entropy of the universe, no decrease.

The Third Law of Thermodynamics

With the approaching of the temperature to absolute zero, the entropy of a system approaches a constant value as defined in the third law of thermodynamics. All the different ground states help in the determination of the entropy value.
