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 does the latent of fusion measure?
The energy required to melt a substance
Calculate heat of fusion?
The heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is typically measured in joules or calories per gram. The specific heat of fusion for water is 334 J/g.
What is the lantent heat of fusion?
The latent heat of fusion is the amount of heat energy required to change a substance from a solid to a liquid at its melting point. It is a physical property specific to each substance and is measured in joules per gram (J/g).
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 energy released by one kilogram of a substance at its freezing point?
The amount of energy released by one kilogram of a substance at its freezing point is known as the latent heat of fusion. This is the energy required to change a substance from a solid to a liquid state without changing its temperature. It is specific to each substance and measured in joules per kilogram.
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 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 energy required to melt one gram of a substance is known as what?
The energy required to melt one gram of a substance is known as the heat of fusion.
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
What a substance does when it releases heat of fusion?
It explodes
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.
