Question
The following information is given for antimony at 1atm:
Th = 1440.00°C
ΔΗ,
vap (1440.00°C) = 1.605 x 10³ J/g
Tm = 631.00°C
Specific heat solid = 0.2090 J/g °C
Specific heat liquid = 0.2590 J/g °C
AHfus (631.00°C) = 161.1 J/g
A 40.40 g sample of liquid antimony at 721.00°C is poured into a mold and allowed to cool to 25.00°C. How many kJ of energy are released in this process?
(Report the answer as a positive number.)
Energy =
kJ
