How much heat in kilojoules is evolved in converting 2.00 mol of
steam at 140 ∘C∘C to ice at -20.0 ∘C∘C? The heat capacity of steam
is 1.84 J/g∘CJ/g∘C and that of ice is 2.09 J/g∘CJ/g∘C.
Remember that if heat is leaving the system, then q is a negative
number and if heat is entering the system, then q is a positive
number.
