How much heat is evolved in converting 1.00 mol of steam at 160.0 ∘C to ice at -50.0 ∘C? The heat capacity of steam is 2.01 J/(g⋅∘C) and of ice is 2.09 J/(g⋅∘C). Express your answer in units of kilojoules Assume the system is at atmospheric pressure.
How much heat (in kilojoules) is evolved in converting 1.00 mol of steam at 145.0 ∘C to ice at -45.0 ∘C? The heat capacity of steam is 2.01 Jg−1∘C−1 and of that ice is 2.09 Jg−1∘C−1.
How much heat in kilojoules is evolved in converting 2.00 mol of steam at 150 ∘ C to ice at -45.0 ∘ C ? The heat capacity of steam is 1.84 J/ g ∘ C and that of ice is 2.09 J/ 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
