Answer: Third law of thermodynamics
Explanation:
The third law of thermodynamics relates the entropy and the temperature of a physical system. This principle, also called Nernst's Postulate states that:
-When reaching absolute zero (0 Kelvin [tex]0k[/tex]), any process of a physical system stops.
-When reaching absolute zero, the entropy reaches a minimum and constant value.
Therefore:
The third law of thermodynamics states the entropy of a perfect crystal at absolute zero is zero.
