Air is contained in a vertical piston-cylinder assembly fitted with an electrical resistor. The atmospheric pressure is 100 kPa and piston has a mass of 50 kg and a face area of 0.1 m² Electric current passes through the resistor, and the volume of air slowly increases by 0,045 n'. The mass of the air is 0.3 kg and its specific energy increases by 42.2 kJ/kg. g=9.8 m/s². Determine the heat transfer from the resistor to air for a system consisting, the air alone,
