Definition of entrophy

(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 .
