Problem
A mass of material exists in its solid form at its melting temperature 100°C. The following processes then occur to the material:
Process 1: An amount of thermal energy Q is added to the material and ¾ of the material melts.
Process 2: An identical additional amount of thermal energy Q is added to the material and the material is now a liquid at 500°C.
What is the ratio of the latent heat of fusion to the specific heat of the liquid for this material?
(a) 800°C
(b) 600°C
(c) 400°C
(d) 200°C
(e) More information is needed to answer this question.
