It is the amount of heat (measured in the proper unit, say calories) required to change a unit mass (measured in the proper units, say gram) of a substance from the solid to the liquid state. This would also be the heat given out by a unit mass of the liquid when it changes to the solid state.

What is Latent heat of fusion dependent?
The latent heat of fusion is dependent on the substance undergoing the phase change from solid to liquid. It is influenced by the specific properties of the material, such as its molecular structure and intermolecular forces. The amount of energy required to overcome these forces and convert the substance from a solid to a liquid state determines the value of the latent heat of fusion.
Which form of heat is absorbed when a solid liquefies?
The heat absorbed when a solid liquefies is called latent heat of fusion. This heat is used to break the bonds between the solid particles, allowing them to move freely and change from a solid to a liquid state.
What does latent heat or fusion mean?
Latent heat of fusion is the energy required to change a substance from solid to liquid at its melting point, without changing its temperature. It represents the energy needed for the molecules to break free from their fixed positions in a solid structure.
What information does the latent heat of fusion give?
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
What are the factors that affect specific latent heat of fusion of a substance?
The amount of energy needed to change the "state of matter" is termed as "latent heat". This is not same for vapourisation (liquid to vapour) or for fusion (solid to liquid). For example, latent of fusion is 79.7 cal whereas latent heat for vapourisation is 541 calories. The latent depends on how closely the atoms and molecules in the matter are closely packed.
What is the energy required to go from a solid to a liquid called?
The latent heat of fusion
Latent heat of fusion is the heat released when?
a solid melts (and the liquid remains at the temperature of the solid).
What do you add when a liquid becomes a solid?
latent heat of fusion.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
Q - What is the difference between latent heat of fusion and latent heat of solidfication?
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
Energy needed to change a material from solid to liquid 3 WORDS?
Heat of Fusion
Why is heat energy needed to melt a solid what is this heat energy called?
This energy is the enthalpy of fusion (or latent heat of fusion).
What is the energy to go from a solid to a liquid called?
The latent heat of fusion
Why is latent heat of vapourisation higher than latent heat of fusion?
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
What is Latent heat of fusion dependent?
The latent heat of fusion is dependent on the substance undergoing the phase change from solid to liquid. It is influenced by the specific properties of the material, such as its molecular structure and intermolecular forces. The amount of energy required to overcome these forces and convert the substance from a solid to a liquid state determines the value of the latent heat of fusion.
The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the?
molar heat of fusion
Which form of heat is absorbed when a solid liquefies?
The heat absorbed when a solid liquefies is called latent heat of fusion. This heat is used to break the bonds between the solid particles, allowing them to move freely and change from a solid to a liquid state.
