Applying Reasoning about Heat Flow
An iron sphere with a mass of 75.00 g is heated to
a temperature of 385.0°C. It is then placed in a
beaker containing 150.0 g H20 at 100.0°C.
Cp. Fe = 0.422 J/g•°C
AHvap, water = 40.7 kJ/mol
How much heat energy must the water absorb to
boil away completely? kJ
AHfus, water = 6.01 kJ/mol
What is the maximum amount of heat the iron can
release to the water? KJ
Cp, water = 4.18 J/g.°C
molar mass of water = 18.00 g/mol
DONE
molar mass of iron = 55.85 g/mol
