Properties Of Solids And Liquids Question 19
Question: The latent heat of vaporization of a substance is always [SCRA 1998]
Options:
A) Greater than its latent heat of fusion
B) Greater than its latent heat of sublimation
C) Equal to its latent heat of sublimation
D) Less than its latent heat of fusion
Show Answer
Answer:
Correct Answer: A
Solution:
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.
