Heat of Fusion can turn a solid substance to a liquad substance

The amount of energy that is needed to melt 1 kg of a substance is known as heat of fusion

Explanation:

Fusion, as a physical process, can be represented as a phase transition (solid to liquid). Therefore, the latent heat of fusion is the change of enthalpy when a substance absorbs energy and passes from a solid state to a liquid at a constant pressure. The difference in intermolecular forces in a liquid phase has an internal energy much greater than a solid one, so solid substances need to absorb heat to melt them and become liquid

they absorb it i think

not sure

you

yay can i have brainliest
