Question

Exception of third law of thermodynamic​

Answer 1

Answer:

If it is not perfect, it is assumed not to be in true thermodynamic equilibrium, and the entropy at absolute zero will not be zero. Because of these so‐called exceptions, some people have been loath to regard the Third Law as a law, on par with the First and Second Laws.

Answer 2

Explanation:

• The third law of thermodynamics states that a system's entropy approaches a constant value as the temperature approaches absolute zero. With the exception of non-crystalline solids (glasses) the entropy of a system at absolute zero is typically close to zero

Explannation

• The third law of thermodynamics has two important consequences: it defines the sign of the entropy of any substance at temperatures above absolute zero as positive, and it provides a fixed reference point that allows us to measure the absolute entropy of any substance at any temperature.
