Physics - Heat & Thermo Question with Solution | TestHub

A given mass $m$ of a hypothetical solid is supplied with heat continuously at a constant rate and the graph shown in the adjacent figure is plotted. If ${\mathrm{L}}_{\mathrm{f}}$ and ${\mathrm{L}}_{\mathrm{v}}$ are latent heats of fusion and latent heats of vaporization and ${\mathrm{S}}_{\ell }$ and ${\mathrm{S}}_{\mathrm{s}}$ are specific heats of liquid and solid respectively. It can be concluded that
