Two solid bodies of equal masses are heated at a uniform rate under identical conditions. The change in temperature in the two cases is shown graphically. What are their melting points?
Find the ratio of their specific heats in solid and latent heats.

Sol. The melting points liquids I and II are 
and 
, respectively. Let 
be the rate of
supply of heat. We note from the graph that liquid 
is heated through 
in 2 units of time and that liquid II is heated through 
in 4 units of time.
Hence, 
We note further that the temperature of I remains constant for 4 units of time and that of II for 2 units of time.
