It is the amount of energy required to change 1kg of solid into a liquid with no temperature change.

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 specific latent heat of fusion for a substance that takes 550 kJ to melt 14 kg at 262 K?
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.
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.
What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
What does the latent of fusion measure?
The energy required to melt a substance
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.
What information does the latent 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 is the energy required to go from a solid to a liquid called?
The 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
What do you add when a liquid becomes a solid?
latent heat of fusion.
What does the latent heat of fusion?
The energy required to melt a substance
What requires more energy the latent heat vaporisation of water or the latent fusion of ice?
The latent heat of vaporisation of water requires more energy. This is because on melting, the intermolecular bonds in water are only weakened whereas on boiling, the bonds are completely broken, which requires a larger amount of energy.
