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....

7. The chemical engineering lab contains a 1.5 m rigid tank installed with a paddle wheel. Suppose this tank is filled with 2.7 kg of carbon dioxide at 100 kPa, and that paddle-wheel work is done on the system until the pressure rises to 150 kPa. Determine the entropy change of the system during this process (kJ/K). You may assume that the tank is well-insulated, and that CO2 is an ideal gas with constant specific heats at RT.
