Hence, entropy can be understood as a measure of molecular disorder within a macroscopic system. The second law of thermodynamics states that an isolated system's entropy never decreases. Such systems spontaneously evolve towards thermodynamic equilibrium, the state with maximum entropy.

Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter.Physically, temperature is a measure of the random agitation of matter and ambient photons, under the effect of thermal fluctuations.n the previous section temperature was defined in terms of the Zeroth Law of thermodynamics. It is also possible to define temperature in terms of the second law of thermodynamics, which deals with entropy. Entropy is a measure of the disorder in a system.
