Question
In CHEM 151 class, engineering students examine
the heat release in a phase transition process. In a
typical experiment, a 70 g of steam at 120°C is
converted to a liquid water at 50 °C. What will
students calculate the heat release in this
experiment? (Specific heat of water = Specific heat
of steam = 4.18 J/°C.g; AHvap
-AHcond= -40.79
kJ/mol; R=8.314 J/mol.K; H2O=18.02 g/mol)
