Question

Latent heat of fusion refers to which changes of state?

Answer 1

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, (or resulting from the release of energy from a substance during transition ...

Answer 2

Step-by-step explanation:

The amount of energy required to change the state of matter at constant temperature is called latent heat.

There are two types of latent heat.

1. Latent heat of fusion: The amount of heat required to convert 1 kg of ice at 0 degree Celsius into 1 kg water at 0 degree Celsius is called latent heat of fusion.

2. Latent heat of vaporization: The amount of heat required to convert 1 kg of water at 100 degree Celsius into 1 kg steam at 100 degree Celsius is called latent heat of vaporization.
