Question

what is specific latent heat of fusion ?​

Answer 1

specific latent heat of fusion :-

the amount of heat energy absorbed at contant temperature by unit mass of a solid to convert into liquid phase is called the specific latent heat of fusion

Answer 2

Answer:

The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. Each substance has two specific latent heats: latent heat of fusion (the amount of energy needed to freeze or melt the substance at its melting point)

Explanation:

The specific latent heat is different for solid to liquid transition and liquid to gas transition. For example, if we want to turn 20 g of ice into water we need Q = 20 g * 334 kJ/kg = 6680 J of energy. To turn the same amount of water into vapor we need Q = 45294 J .
