Is entropy zero for elements under standard conditions?

Answer 1

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?

No, entropy is not zero for elements under standard conditions. Entropy is a measure of the randomness or disorder of a system, and even at standard conditions, elements still possess some level of entropy due to the motion of their particles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
