What is the term used to define the temperature at which the solid and liquid phases are in equilibrium?

Question

anonymous · Answer

heat of fusion is the energy at 1 ATM that is used or released(I forget which) when a substance goes from solid to liquid.

aaronq · Answer

the temperature is called the $\sf melting~point$.

anonymous · Answer

yes and the total energy(not the average) at that same period of time is called the heat of fusion.

Nope, you're confused. The question is asking for a temperature. "What is the term used to define $\sf the ~temperature$.." the latent heat/enthalpy of fusion is the change in enthalpy when a substance changes phases - not a temperature but a change in internal energy. http://en.wikipedia.org/wiki/Enthalpy_of_fusion
