The following information is given for aluminum at latm:
T = 2467.00°C
AHvap (2467.00°C) = 1.053 × 10ª J/g
AĦfs (660.00°C) = 398.4 J/g
Tm = 660.00°C
Specific heat solid = 0.9000 J/g °C
Specific heat liquid = 1.088 J/g °C
A 26.30 g sample of liquid aluminum at 878.00°C is poured into a mold and allowed to cool to 30.00°C.
How many kJ of energy are released in this process?
(Report the answer as a positive number.)
Energy =
kJ
