[100 PTS!] Suppose a substance has a heat of fusion equal to 45 cal/g and a specific heat of 0.75 cal/g°C in the liquid state. If 5.0 kcal of heat are applied to a 50-g sample of the substance at a temperature of 24°C, will its new temperature be? What state will the sample be in? (melting point of the substance = 37°C; specific heat of the sold = 0.48 cal/g°C; boiling point of the substance = 700°C) Show your work.
