There exist three laws of the thermodynamics:

a) First Law: Energy can neither be created nor it is destroyed. It only changes the forms. In any of the process within an isolated system, the total energy stays the same.

b) Second Law: Whenever the two isolated systems in the detached however nearby regions of the space, each in the thermodynamic equilibrium in itself, however not in the equilibrium along with each other at first, are at some time enabled to interact, breaking the isolation which divides the two systems, and they exchange the matter or energy, they might ultimately reach the mutual thermodynamic equilibrium. Sum of the entropies of initial, isolated systems is less than or equal to the entropy of final exchanging systems. In the process of reaching a new thermodynamic equilibrium, entropy has increased.

c) Third Law: This law states that as the temperature reaches the absolute zero, entropy of the system decreases to a minimum.
