entropy The degree of disorder in a system. As energy is transferred from one form to another, some is lost as heat; as the energy decreases, the disorder in the system&emdash;and thus the entropy&emdash;increases.
entropy
(en-truh-pee) [Gk. en, in + trope, turning]
A quantitative measure of disorder or randomness, symbolized by S.

Entropy A measure of the degree of randomness or disorder in a system; denoted by the symbol S in thermodynamics, the change in entropy (.S) increases when a system becomes more disordered and decreases when the system becomes more ordered, ...
[edit] Entropy and cooperativity
In all of the above types of cooperativity, entropy plays a role. For example in the case of oxygen binding to haemoglobin, the first oxygen has four different places where it can bind.
entropy A measure of the degree of disorganization of a system; how much energy in a system has become so dispersed (usually as heat) so that it is no longer available to do work. The higher the entropy, the more the disorder.
equal to the entropy times the absolute temperature

" This is also commonly referred to as entropy. A watchspring-driven watch will run until the potential energy in the spring is converted, and not again until energy is reapplied to the spring to rewind it.
The confusion was originated when some properties associated with the entropy were subordinated like alternatives to explain biotic features; for example, order, complexity, etc.

(Science: radiobiology) variable generally used for either entropy or the Poynting flux of electromagnetic wave energy (context makes clear which is meant).
free energy(G) - energy that can be extracted from a system to drive reactions. Takes into account changes in both energy and entropy.
