The Second Law of Thermodynamics states that the total entropy of an isolated system always increases over time this means that as energy is transferred or transformed, more and more of it is wasted, and there is a natural tendency of any isolated system to degenerate into a more disordered state. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past. (Refer to the Laws of Thermodynamics)
