... A solid like glass that has imperfections built into it will not have an entropy of 0 even at 0 K because not a perfect crystal so still has some randomness left in it Another way to say third law is - It is NOT possible to reach absolute zero Note: At absolute zero all atomic motion stops atoms and ...

... is the amount of heat reversibly exchanged with the surroundings at temperature T . For an isolated system, δQ = 0. Therefore, in an isolated system the entropy is constant in thermodynamic equilibrium and it has an extremum because dS = 0. It is found that in every situation this extremum is a maxi ...
