Third law of thermodynamics: Nonetheless

Nonetheless, the combination of these two ideals constitutes the basis for the third law of thermodynamics: the entropy of any perfectly ordered, crystalline substance at absolute zero is zero. The entropy of a pure, perfect crystalline substance at 0 K is zero. Learn what the third law of thermodynamics states, how it relates to entropy and absolute zero, and how it can be used to calculate the absolute entropy of a substance. Find examples, mathematical equations, and frequently asked questions about this law of thermodynamics. The third law of thermodynamics is defined as assigning an entropy equal to zero at absolute zero temperature (0 K) for any pure compound in a stable and perfectly crystalline state. This law allows for the expression of the absolute value of entropy in relation to internal energy.
