... • The third law of thermodynamics states that the entropy of a perfect crystal of any pure substance approaches zero as the temperature approaches absolute zero. • Because S is explicitly known (= 0) at 0 K, S values at other temps can be calculated. • The entropy of one mole of a chemical substance ...
