Question

A given mass m of a hypothetical solid is supplied with heat continuously at a constant
rate and the graph shown in the below figure is plotted. If L, and Ly are latent heats of
fusion and latent heats of vaporization and S, and S, are specific heats of liquid and solid
respectively. It can be concluded that:-
temperature (°C)
Boiling
2001
30H
melting
10

100 120
t(sec)​

Answer 1

Answer:

The correct answer is Lf > Sv. Sf < Ss .

Explanation:

A given mass m of a hypothetical solid is supplied with heat continuously at a constant rate and the graph shown in the below figure is plotted.

If L and Ly are latent heats of fusion and latent heats of vaporization and S, and S, are specific heats of liquid and solid respectively.

So, I have done the below calculations for this question please check the attached image for this.
