Answer 2

1) Latent Heat of fusion -: The heat energy required by 1kg of a solid at its melting point to change into the liquid state without any rise in temperature is known as its latent heat of fusion.
2) Melting point -: The fixed temperature at which a solid changes into liquid on heating is called the melting point of solid
3) Fusion -: Physical change of a solid into its liquid state at a constant temperature.
