# An AC would surely help!

A $$\text{solid}$$ initially at $$20\text{ }^\circ C$$ is heated. The graph given above shows variation in temperature with the amount of heat energy supplied to it. Now, if the specific heat capacity of solid is $$2\text{ J}{g}^{-1}{\text{ }^\circ C}^{-1},$$ calculate

(i) the mass of the solid, and
(ii) the specific latent heat of fusion of solid.

Submit your answer as the sum of (i) (in grams) and (ii) (in $$\text{ J/g}$$).
