CIDE DICTIONARY

Entropy, n. [Gr. a turning in; in + a turn, fr. to turn.].

 A certain property of a body, expressed as a measurable quantity, such that when there is no communication of heat the quantity remains constant, but when heat enters or leaves the body the quantity increases or diminishes. If a small amount, h, of heat enters the body when its temperature is t in the thermodynamic scale the entropy of the body is increased by h . The entropy is regarded as measured from some standard temperature and pressure. Sometimes called the thermodynamic function.  [1913 Webster]
"The entropy of the universe tends towards a maximum."  [1913 Webster]
