A closed, rigid tank fitted with a paddle wheel contains 1.6 kg
of air, initially at 200oC, 1 bar. During an interval of
10 minutes, the paddle wheel transfers energy to the air at a rate
of 1 kW. During this time interval, the air also receives energy by
heat transfer at a rate of 0.5 kW. These are the only energy
transfers. Assume the ideal gas model for the air, and no overall
changes in kinetic or potential energy. Do not assume specific
heats are constant.
Determine the change in specific internal energy for the air, in
kJ/kg, and the final temperature of the air, in oC.
