Question

what is the difference between latent heat of fusion and specific latent heat of fusion?

Answer 1

Specific latent heat is the amount of heat required to raise the temperature of a body of mass 1kg by 1k(kelvin).


while latent heat is the amount of heat released or absorbed by a body when it changes its state. there is no change in temperature.

in other words we can say..

Specific heat is the amount of heat required to raise the temperature of a substance a certain amount. Latent heat is the amount of heat released during a change of state, i.e. the boiling of water or the melting of ice.

Answer 2

Latent Heat- Amount heat energy released or absorbed by a substance to change its physical state at constant temperature

Latent Heat of Fusion- Amount of heat energy required to change a unit mass of ice to water at constant temperature or 0 degrees Celcius
