15. While casting a silver ornament, a silver-47-8 smith pours 0.12 kg of molten silver at 1010°C into a 2.40-kg iron mold at a temperature of 35°C. What will be the equilibrium temperature of the silver casting and mold? Use information in the following table, and assume no thermal energy is lost to the surrounding environment. 'C '90x/0 128 ky Material Iron Iron Iron (s) Silver Silver (s) Silver (1) Silver Table 12-2 Variable Heat of fusion Melting point Specific heat Heat of fusion Specific heat Specific heat Melting point 0. 12X Value 2.66X105 J/kg 1535°C 450 J/kg-°C 1.04X105 J/kg 235 J/kg-°C 290 J/kg-°C 960°C 15.
