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.

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 does the latent of fusion measure?
The energy required to melt a substance
Calculate heat of fusion?
The heat of fusion is:Q = specific heat x mass
Which heat changes the state of a substance without changing its temperature?
both the heat of fusion and the heat of vaporization
Define latent heat of fusion and latent heat of vapourisation?
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
How does the presence of hydrogen bonds affect the heat of fusion of a substance?

What is wrong with this statement, "As a substance freezes, it absorbs energy equal to its enthalpy of fusion"?
There is nothing inherently wrong with the statement "As a substance freezes, it absorbs energy equal to its enthalpy of fusion." In fact, this statement is a well-established scientific principle known as the Enthalpy of Fusion. When a substance changes from a liquid phase to a solid phase (freezing), it undergoes a phase change that requires a specific amount of energy to overcome the intermolecular forces holding the substance together. This energy absorbed is known as the Enthalpy of Fusion, and it is dependent on the substance and specific conditions. Therefore, this statement accurately describes the process of freezing and provides important information about how substances behave during phase changes.
What is the amount of energy required to raise the temperature of 1 kilograms of a substance by 1 kelvin is called?
Specific heat is the amount of heat needed to melt one kilogram of a substance...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.
What a substance does when it releases heat of fusion?
It explodes
The energy required to melt one gram of a substance is known as what?
heat of fusion
What is enthalpy of fusion vaporization?
Enthalpy of fusion/vaporization is the amount of energy added to a system to melt of boil a substance or the amount of energy removed from a system to condense or freeze a substance.

When a substance changes from solid to liquid is called?
fusion
What does the latent of fusion measure?

Calculate heat of fusion?
The heat of fusion is:Q = specific heat x mass
