A mass of a material exists in its solid form at its melting temperature 10°C. The following processes then occur to the material.
Process I : An amount of thermal energy Q is added to the material and 3/4 of the material melts.
Process II : An identical additional amount of thermal energy Q is added to the material and the material is now a liquid at 50°C.
What is the ratio of the latent heat of fusion to the specific heat of the liquid for this material ?
