Verified Answer
Latent heat of fusion is the amount of heat energy required to change:...
The enthalpy of fusion is a latent heat, because during melting the heat energy needed to change the substance from solid to liquid at atmospheric pressure is latent heat of fusion, as the temperature remains constant during the process.

Latent Heat of Fusion
Definition: The amount of heat energy required to change 1 kg of a solid into its liquid state at its melting point is known as latent heat of fusion.
Explanation:
When a solid is heated, its temperature increases until it reaches its melting point. At this point, the solid starts to melt and its temperature remains constant until all the solid has turned into a liquid. The heat energy required to change the state of the solid into a liquid at its melting point is known as the latent heat of fusion.
For example, the latent heat of fusion of ice is 334 J/g. This means that to melt 1 kg of ice, 334000 J of heat energy is required. This heat energy is used to break the bonds between the molecules of the solid, so that they can move freely and become a liquid.
Options:
a) 1 kg of solid into its gaseous state at its boiling point - This is referring to the latent heat of vaporization, which is the amount of heat energy required to change 1 kg of a liquid into its gaseous state at its boiling point.
b) 1 kg of liquid into its solid state at its freezing point - This is referring to the latent heat of fusion, which is the amount of heat energy required to change 1 kg of a solid into its liquid state at its melting point.
c) 1 kg of liquid into its gaseous state at its boiling point - This is referring to the latent heat of vaporization, which is the amount of heat energy required to change 1 kg of a liquid into its gaseous state at its boiling point.
d) 1 kg of solid into its liquid state at its melting point - This is the correct answer, as explained above.

Latent heat of fusion is the amount of heat energy required to change:...
The correct answer is d because the latent heat of fusion is the heat required to change the solid into liquid form without increasing in temperature and it is the hidden heat which work as a state changer
