Question

What can be the value of absolute entropy of free element?
(A) Always negative
(B) Always positive
(C) Always zero
(D) Zero at 273 K

Answer 1

Entropy of free element is always positive.

Absolute entropy indicates the entropy change of a substance taken from absolute zero to a given temperature.

In statistical mechanics, entropy is an extensive property of thermodynamic system.

It is closely connected with the number Ω of microscopic configurations which are consistent with macroscopic quantities which characterize the system like pressure, volume and temperature.
