Two different liquids of same mass are kept in two identical vessels, which are placed in a freezer that extracts heat from them at the same rate causing each liquid to transform into a solid. The schematic figure below shows the temperature T vs time t plot for the two materials. We denote the specific heat in the liquid statusto be $C_{L 1}$ and $C_{L 2}$ for materials 1 and 2 respectively, and latent heats of fusion $U_{1}$ and $U_{2}$ respectively.
