Question: An insulated pistoncylinder device initially contains 0.3 m3 of carbon dioxide at 200 kPa and 27C. An electric switch is turned on, and a 110-V

An insulated piston–cylinder device initially contains 0.3 m3 of carbon dioxide at 200 kPa and 27°C. An electric switch is turned on, and a 110-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. Determine the current that passes through the resistance heater.
