Expert Answer
Definition: The amount of heat required to convert a unit mass of a solid at its melting point into a liquid without an increase in temperature.
The energy required to change a gram of a substance from the solid to the liquid state without changing its temperature is commonly called it's "heat of fusion". This energy breaks down the solid bonds, but leaves a significant amount of energy associated with the intermolecular forces of the liquid state.
