Heats of fusion of the elements (data page)

The heat of fusion, also known as the enthalpy of fusion, is the amount of energy required to change a substance from a solid to a liquid at its melting point. This property varies among different elements and compounds. Here’s a general overview of the heats of fusion for some common elements (values are approximate and can vary based on the source): 1. **Hydrogen (H)**: 0.117 kJ/mol 2.
