### Calculating Standard Entropy of Fusion

Why does one use freezing temperature to calculate the entropy of fusion at a substance's melting point? (Reference: 6th ed-Self Test 9.8B)

Because at the freezing temperature is when it goes from liquid to solid, so it's also the melting point, where it goes from solid to liquid. So you use the same temperature.

Enthalpy of fusion is the amount of heat energy required to change the state of a substance from a solid to a liquid, at its melting point. When a solid becomes a liquid, it's called melting or fusion.
