12.3—The entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect

Understand that the entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect crystals at zero kelvin have zero entropy.

Use —the entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect to connect the rule to the data and decision in the question.

This matters because —the entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The entropy of a substance increases with temperature, that entropy increases as solid → liquid → gas and that perfect is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
