Latent heat of fusion (or enthalpy of fusion) is a characteristic of a substance, rather than a chemical bond. If you mean enthalpy of reaction then the lowest absolute values are for the bonds in H2, F2, and Cl2 as gases, which are zero. One low (and negative) value is for cuprous sulphate. Please see the link.
Heat of fusion is a physical property. It describes the amount of heat energy required to change a substance from a solid to a liquid phase at its melting point, without altering its chemical composition.
True. The molar enthalpy values for fusion (also known as the enthalpy of fusion) are independent of the direction of the process. This means that the enthalpy change for melting a substance is equal in magnitude, but opposite in sign, to the enthalpy change for freezing the substance.
The enthalpy of a chemical reaction is the change of heat during this reaction.
The enthalpy of a chemical reaction is the change of heat during this reaction.
For example the enthalpy of formation.

No, evaporation is a physical process, not a chemical property. It involves the transformation of a substance from a liquid to a gas, without changing its chemical composition.
Enthalpy is a thermodynamic property of a thermodynamic system.
The heat energy, or enthalpy, associated with a solid to liquid transition is the enthalpy of fusion and that associated with a solid to gas transition is the enthalpy of sublimation.
The enthalpy of fusion is the heat energy absorbed or released when a substance changes from solid to liquid at its melting point. The enthalpy of vaporization is the heat energy absorbed or released when a substance changes from liquid to gas at its boiling point.
The enthalpy of high-density polyethylene (HDPE) can vary depending on its specific form and conditions. However, HDPE typically has a heat of fusion enthalpy of around 110 J/g.
· General chemical properties: - Pauling electronegativity - Period - Group - Flammability - Corrosivity - Heat of combustion - Enthalpy of formation Valence (oxidation states)
The enthalpy of fusion of a substance (H fusion) tells us how much energy is required to melt one gram of the substance. By dividing the energy input (1 kJ) by the enthalpy of fusion, you can calculate the mass of the substance that the energy will melt. It's a simple ratio: mass = energy input (kJ) / enthalpy of fusion (kJ/g).
