How much heat in kilojoules is evolved converting 1.50 moles of steam at 150 Celsius to -20.0 Celsius? The heat capacity of steam is 1.84 J/ g*C and that of ice is 2.09 J/ g*C. Remember that if the heat is leaving the system, then q is a negative number and if heat is entering the system, then q is a positive number.
Under normal atmospheric pressure, nitrogen boils (and condenses) at -196oC. When 7.7 g of nitrogen gas at -196oC was put into a dewar flask initially at -260oC, their temperatures reach -210oC.
