The following information is given for aluminum at 1 atm:

boiling point = 2.467×10³ °C	H_vap(2.467×10³ °C) = 1.053×10⁴ J/g
melting point = 660.0 °C	H_fus(660.0 °C) = 398.4 J/g
specific heat solid = 0.9000 J/g°C
specific heat liquid = 1.088 J/g°C

A 46.20 g sample of liquid aluminum at 877.0 °C is poured into a mold and allowed to cool to 29.0 °C. How many kJ of energy are released in this process. Report the answer as a positive number.
