    I. Energy can be neither created nor destroyed. It is conserved.

    II. For any spontaneous process, there is always an increase in the entropy (disorder) of the universe.

    III. The entropy of any pure crystalline substance at absolute zero is zero.

    Zeroth Law/ Third Law in other words states that if A and B are in Thermal Equilibrium And if B & C are also in thermal equilibrium than A and C are also in thermal Equilibrium
