Examples of Latent Heat of Fusion
There are various examples of latent heat of fusion. Some of these values are discussed in the following headings.
Latent Heat of Fusion of Ice
Latent heat of fusion of ice is the heat required to change the state of ice, i.e. it is the amount of heat required to change the ice into the water without changing its temperature. The latent heat of Ice is 334 J/g.
Latent Heat of Fusion of Other Substances
The latent heat of Fusion for various elements and compounds can be calculated using the formula which we will learn in further headings. The latent heat of fusion for some common elements is given in the following table:

Latent Heat of Fusion
Latent Heat of Fusion is one of the latent heats in chemistry like the latent heat of vaporization and latent heat of sublimation. When a substance is changing its phase from liquid to solid or solid to the gas of gas to a liquid, this latent heat comes in handy to find the energy of the reaction. Latent Heat of Fusion is related to the solid-to-liquid phase change. In this article, we will explore all the topics related to the latent heat of fusion and its formula. We’ll also learn about the latent heat of fusion for various different elements as well as compounds.
Let’s start our learning about the concept with the name “Latent Heat of Fusion”.
