Air is contained in a piston-cylinder arrangement with an initial volume of 0.02 m³ and at an initial temperature of 77°C. In this state, a manometer installed in the system is 400 kPa. Heat is added in the amount of 42 kJ and work is done by a paddle wheel until the temperature reaches 527°C. If the pressure is kept constant, how much work of the paddle wheel should be added to the gas? Consider the properties of the gas as constants; take the system is well thermally insulated. (RAr~0.2870 kJ/kg - K).
