“In thermodynamics, entropy (usual symbol S) is a measure of the number of specific ways in which a thermodynamic system may be arranged, commonly understood as a measure of disorder. According to the second law of thermodynamics the entropy of an isolated system never decreases; such systems spontaneously evolve towards thermodynamic equilibrium, the configuration with maximum entropy. Systems which are not isolated may decrease in entropy. Since entropy is a state function, the change in the entropy of a
