Question

A solid material is supplied with heat at constant rate and the temperature of the material changes as shown. From the graph, the FALSE conclusion drawn is

• A. $AB$ and $CD$ of the graph represent phase changes
• B. $AB$ represents the change of state from solid to liquid
• C. latent heat of fusion is twice the latent heat of vaporization
• D. $CD$ represents change of state from liquid to vapour
• E. latent heat of vaporization is twice the latent heat of fusion

Answer 1

Answer: (C)

Correct answer is (c) latent heat of fusion is twice the latent heat of vaporization
