which thermochemical law describes the entropy of a system for a perfect crystal as zero at absolute zero? zeroth law of thermodynamics first law of thermodynamics second law of thermodynamics third law of thermodynamics

which thermochemical law describes the entropy of a system for a perfect crystal as zero at absolute zero? zeroth law of thermodynamics first law of thermodynamics second law of thermodynamics third law of thermodynamics

Answer

Brief Explanations:

The Zeroth Law relates to thermal equilibrium. The First Law is about energy conservation (ΔU = Q - W). The Second Law deals with entropy direction (e.g., heat flow, disorder increase). The Third Law of Thermodynamics states that the entropy of a perfect crystal is zero at absolute zero (0 K). So the correct law is the Third Law.

Answer:

D. Third Law of Thermodynamics
