Question

Define latent of fusion and latent heat of vapourization . Also write their S.I units.

Answer 1

1. Latent heat of vapourisation: The energy or heat absorbed by the substance to convert into vapours is called as latent heat of vaporisation. SI unit is kJ kg^-1.


2. Latent heat of fusion: The energy or heat absorbed by the substance to convert into liquid is called latent heat of fusion. SI unit is kJ kg^-1.
