Definition of entrophy
1. entropy [ n ] (thermodynamics) a measure of the amount of energy in a system that is available for doing work; entropy increases as matter and energy in the universe degrade to an ultimate state of inert uniformityUsed in print:
(Frank Oppenheimer, "Science and Fear-- A Discussion...)
As cells coalesced into organisms , they built new `` unnatural '' and internally controlled environments to cope even more successfully with the entropy increasing properties of the external world .
(Harry H. Hull, "The Normal Forces and Their Ther...)
There is a well-known relationship between probability and entropy which states that * * f , where \q is the probability that state ( i.e. , volume for an ideal_gas ) could be reached by chance alone .
This conformational_entropy is , in this case , equal to the usual entropy , for there are no other changes or other energies involved .Synonyms entropy randomness s Related Terms ectropy physical_property physical_phenomenon conformational_entropy thermodynamics
2. entropy [ n ] (communication theory) a numerical measure of the uncertainty of an outcome
