Question

What is latent heat of fusion ?

Answer 1

hi there,

latent heat of fusion:- it is the heat required to change 1 kg solid substance into liquid state at the melting point of that substance.

its SI unit is Joule/kg.

let's take an example:-

amount of heat required to melt ice at 0°C  into liqiud at 0°C, this is known as latent heat.

hope it helps..

Answer 2

Hi friend,

The heat that we supply during the melting of a solid is called as latent heat if fusion.

It is the amount of heat energy that we need to Change 1 kg of mass of solid to liquid at its atmospheric pressure at its melting point.

SI unit of latent heat or fusion is JOULES PER KILOGRAM (J/kg).

For example- When we held ice in our hand, it melts, this is because the heat is provided by our hand and ice absorbs the heat and melts. Hence this is an example of latent heat of fusion.

Hope it helps.....
