Question
6. At a foundry, 25kg of molten aluminum with a temperature of660.4 degC is poured into a mold. If this is carried out in a roomcontaining 130kg of air at 25deg C, what is the temperature of theair after the aluminum is completely solidified? Assume that thespecific heat capacity of air is 1.0x103 J/kgdegC. 6. At a foundry, 25kg of molten aluminum with a temperature of660.4 degC is poured into a mold.
