22 //! Defined as a property which changes as a system undergoes
23 //! reversible change. The change in entropy is quantified as
24 //! the change in energy per degree of temperature. All real
25 //! changes are at least partially irreversible so entropy
26 //! is increased by change. Entropy can be viewed as a
27 //! measure of the molecular disorder of a system, or as the
28 //! unavailability of its internal energy to do work in a
30 //! A change in entropy is measured in joules per degree kelvin.
