The latent heat of vaporization of a substance is always

Greater than its latent heat of fusion

Greater than its latent heat of sublimation

Equal to its latent heat of sublimation

Less than its latent heat of fusion

Solution

(a)The latent heat of vaporization is always greater than latent heat of fusion because in liquid to vapour phase change there is a large increase in volume.

Hence more heat is required as compared to solid to liquid phase change.
