Report Error
A
AB and CD of the graph represent phase changes
2%
B
AB represents the change of state from solid to liquid
19%
C
latent heat of fusion is twice the latent heat of vaporization
38%
D
CD represents change of state from liquid to vapour
6%
E
latent heat of vaporization is twice the latent heat of fusion
6%
Solution:
The option is false because the latent heat of vaporization is twice the latent heat of fusion.
