Answer:
A 55.0*C sample of water vapor, initially at 155C is cooled at atmospheric pressure, producing ice at -55C. Calculate the amount of heat energy lost by the water sample in this process, in kJ. Use the following data: specific heat capacity of ice is 2.09 J/g*K; specific heat capacity of liquid water is 4.18J/g*K; specific heat capacity of water vapor is 1.84 J/g*K; heat of fusion of ice is 336 J/g; heat of vaporization of water is 2260 J/g.
