Question: An insulated piston - cylinder device initially contains 0 . 3 m 3 of carbon dioxide at 2 0 0 kPa and 2 7

An insulated piston-cylinder device initially contains 0.3 m3
of carbon dioxide at 200 kPa and 27\deg C. An electric switch is turned on, and a 160.0-V source supplies current to a resistance heater inside the cylinder for a period of 10 min. The pressure is held constant during the process, while the volume is doubled. The gas constant and molar mass of CO2 are R =0.1889 kPam3/kgK
and M =44 kg/kmol (Table A-1). The specific heat of CO2 at the average temperature of Tavg =(300+600)/2=450 K
is cp, avg =0.978 kJ/kg\deg C
(Table A-2b).Determine the current that passes through the resistance heater ___ A.
