Yes, heat fusion occurs in a substance when it changes from a solid to a liquid state without a change in temperature. This process involves the absorption of heat energy to break the bonds holding the molecules together in a solid, allowing them to move freely in a liquid state.
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
The specific latent heat of fusion can be calculated by dividing the energy required to melt the substance by the mass of the substance. In this case, the specific latent heat of fusion would be (550 kJ) / (14 kg) = 39.29 kJ/kg.
The latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is a physical property specific to each substance and is measured in joules per gram (J/g).
The heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is typically measured in joules or calories per gram. The specific heat of fusion for water is 334 J/g.
Heat of fusion is called the latent heat of fusion because it is the heat energy required to change a substance from a solid to a liquid phase, or vice versa, without a change in temperature. This heat energy is "hidden" as it is being used to break the intermolecular bonds holding the substance together, rather than increasing its temperature.
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
The energy required to melt one gram of a substance is known as the heat of fusion.

The measurement of how much heat energy is required for a substance to melt is called the heat of fusion. It is the amount of energy required to change a substance from a solid to a liquid at its melting point.
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
Because of the heat of fusion the ice is now water
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
The energy required to melt a substance
The latent heat of fusion is defined as the heat energy required to convert a kg of a substance of liquid into solid of the same substance without a change of temperature. Q = mL where Q = Heat Energy in joules, m=mass of substance, L= Latent heat of fusion Taking units, [J] = [kg] [L] [L] = [J]/[kg] so units of latent heat of fusion are joules.kg-1
That's the heat of fusion.
