A 500 G Sample of Water Vapor, Initially at 155°C Is

Multiple Choice

A 5.00 g sample of water vapor, initially at 155°C is cooled at atmospheric pressure, producing ice at −55°C. 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 4.18 J/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.

A) 15.6 kJ
B) 10.2 kJ
C) 5.4 kJ
D) 3.2 kJ
E) 1.6 kJ
