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

  1. A B and C D of the graph represent phase changes    
  2. A B represents the change of state from solid to liquid    
  3. Latent heat of fusion is twice the latent heat of vaporization    
  4. C D represents change of state from liquid to vapour    

The correct answer is: Latent heat of fusion is twice the latent heat of vaporization
