The delta H fusion, or enthalpy of fusion, represents the amount of energy required to convert a unit mass of a solid into a liquid at its melting point without changing its temperature. To calculate the energy needed to melt a specific mass of solid, you multiply the mass of the solid by the delta H fusion value. The formula can be expressed as ( Q = m \times \Delta H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( \Delta H_f ) is the enthalpy of fusion. This calculation provides the total energy necessary to achieve the phase transition from solid to liquid.

Heat of Fusion
The amount of energy needed to change a given mass of ice to water at constant temperature is called the heat of fusion. This is the heat energy required to change a solid to a liquid at its melting point.
The energy released is called the latent heat of fusion. This energy is needed to overcome the attractive forces between the particles of the substance to allow them to transition from a liquid to a solid state.

This energy is the enthalpy of fusion (or latent heat of fusion).
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.

The formula for calculating the energy needed to melt a mass of a solid is Heat energy = mass x specific heat capacity x ΔT + mass x heat of fusion. This formula includes the specific heat capacity of the material, the change in temperature, and the heat of fusion required to melt the material.
Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.
Heat of Fusion
The heat of fusion is the amount of energy needed to change a substance from a liquid to a solid. To calculate the energy released when a mass of liquid freezes, you would use the equation Q = m * Hf, where Q is the energy released, m is the mass of the substance, and Hf is the heat of fusion.
