What else can I help you with?
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (latent) heat of fusion.
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.
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.
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.
Why is heat energy needed to melt a solid. What is this heat energy called?
Heat energy is needed to melt a solid because it provides the molecules in the solid with enough kinetic energy to overcome the forces holding them in a rigid structure. The specific heat energy required to melt a solid at its melting point is called the latent heat of fusion.
What is the energy required to go from a solid to a liquid called?
The latent heat of fusion
What is the energy to go from a solid to a liquid called?
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
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).
The amount of energy involved in melting a substance without changing its temperature is called the?
It is called the enthalpy of fusion of a substance, also known as (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 is the difference between latent heat of fusion and latent heat of vapourization?
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
When a substance goes from a solid to a liquid state without a change in temperature the heat added during the transformation is called?
That's the heat of fusion.
The temperature at which matter changes from a liquid to a solid is called?
The latent heat of fusion. ____ Freezing point
What is the energy required to go from 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.
