Four kilograms of carbon monoxide (CO) is contained in a rigid tank with a volume of 1 m3. 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 10 kJ/kg. If no overall changes in kinetic and potential energy occur, determine
(a) the specific volume at the final state, in m3/kg.
(b) the energy transfer by work, in kJ.
(c) the energy transfer by heat transfer, in kJ, and the direction of the heat transfer.
