Four kilograms of carbon monoxide (CO) is contained in a rigid tank with a volume of 1m31m 3 . The tank is fitted with a paddle wheel that transfers energy to the CO at a constant rate of 14 W for 1 h. During the process, the specific internal energy of the carbon monoxide increases by 10kJ/kg10kJ/kg. If no overall changes in kinetic and potential energy occur, determine:
a. the specific volume at the final state.
b. the energy transfer by work
c. the energy transfer by heat transfer, and the direction of the heat transfer.
