QU ESTION ' One cubic meter of a certain eutectic alloy is heated in a crucible from room temperature to 100°C above its melting point for casting. The alloy's density = 7.5 g/cm3, melting point = 800°C, specific heat=0.33 "3°C in the solid state and 0.29 J/g°C in the liquid state; and heat of fusion = 160 1/3. a. calculate, i. the heat to raise the temperature to the melting point ii. the heat to raise the molten metal to the desired temperature for pouring. b. How much heat energy (total) must be added to accomplish the heating, assuming no losses?
