The entropies are NON-ZERO.................


The third law of thermodynamics states that the entropy of a perfect crystal at #0*K# is ZERO. And thus most elements, especially gaseous elements, have substantial entropies under standard conditions. These entropies can be calculated by standard means, and they are extensively tabulated.

Why should the entropies of elemental gases be intrinsically greater than the entropies of elements in condensed phases?
