The amount of energy it takes to boil a substance

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.
Why is heat of fusion called the latent heat of fusion?
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.
Formula of latent heat of fusion?
The formula to calculate the latent heat of fusion is Lf = Q / m, where Lf is the latent heat of fusion, Q is the amount of heat added or removed during the phase change, and m is the mass of the substance undergoing the phase change.
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 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.
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 is the energy required to go from a solid to a liquid called?
The latent heat of fusion

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 is SI unit of latent heat of fusion?
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
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.
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 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.
Energy needed to change a material from solid to liquid 3 WORDS?
Heat of Fusion
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
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
