Q. The latent heat of vaporization of a substance is always
A) Greater than its latent heat of fusion
B) Greater than its latent heat of sublimation
C) Equal to is latent heat of sublimation
D) Less than its latent of fusion
Explanation
(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
