Third Law of Thermodynamics
</dt>
The statement that every substance has a finite positive entropy, and
that the entropy of a crystalline substance is zero at the temperature of
absolute zero. See thermodynamic
probability. Modern quantum theory has shown that the entropy of crystals
at 0 degrees absolute is not necessarily zero. If the crystal has any
asymmetry, it may exist in more than one state; and there is, in addition, an
entropy residue deriving from nuclear spin.
