entropy

熵

En·tro·py n. 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.

*The entropy of the universe tends towards a maximum.* --*Clausius.*

entropy

n 1: (communication theory) a numerical measure of the

uncertainty of an outcome; "the signal contained

thousands of bits of information" [syn: information, selective

information]

2: (thermodynamics) a thermodynamic quantity representing the

amount of energy in a system that is no longer available

for doing mechanical work; "entropy increases as matter

and energy in the universe degrade to an ultimate state of

inert uniformity" [syn: randomness, S]
