entropy
(gcide) | Entropy \En"tro*py\, n. [Gr. ? a turning in; ? in + ? a turn,
fr. ? to turn.] (Thermodynamics)
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 / t. The entropy is regarded as measured from
some standard temperature and pressure. Sometimes called the
thermodynamic function.
