A closed, rigid tank having a volume of 1 m3 contains a mixture carbon dioxide (CO2) and water vapor initially at 70°C and 200 kPa The mass of water vapor in the tank is 0.10 kg.
The tank contents are cooled to 20°C. Determine the
(a) mass of CO2 in the tank
(b) heat transfer from the tank during the cooling process, in kJ.
