Five kilograms of carbon monoxide (CO) is contained in a rigid tank with a volume of 2 m . The tank is fitted with a paddle wheel that transfers energy to the CO at a constant rate of 12 W for 1 hour. During the process, the specific internal energy of the carbon monoxide increases by 20 kJ/kg. If no overall changes in kinetic and potential energy occur. Determine: a. The specific volume at the final state (in m^3/kg).
b. The energy transfer by work (in kJ).
c. The energy transfer by heat (in kJ) and the direction of heat transfer.
