## FAQ

### What Is Meant By Enthalpy Of Fusion?

Latent heat of fusion, also known as enthalpy of fusion, is the amount of energy that must be supplied to a solid substance (typically in the form of heat) in order to trigger a change in its physical state and convert it into a liquid (when the pressure of the environment is kept constant).

### What Is Enthalpy Of Fusion A Level Chemistry?

The enthalpy of fusion is the amount of energy required to break these intermolecular forces and turn a solid into a liquid. The stronger the intermolecular forces between molecules in a solid, the higher the enthalpy of fusion will be.

### Why Is Enthalpy Of Fusion Important?

It can be used to determine the freezing point depression of solute. The magnitude of heat of fusion and heat of vaporization is related to the nature and strength of forces which hold the molecules of the solvent together in the solid or the liquid state.

### What Is Enthalpy Of Fusion At Melting Point?

The enthalpy of fusion of a substance, also known as latent heat, is a measure of the energy input, typically heat, which is necessary to convert a substance from solid to liquid state. The melting point of a substance is the temperature at which it changes state from solid (crystalline) to liquid (isotropic melt).
