Air is contained in a variable-load piston{cylinder device equipped with a stirring paddle wheel. Initially, air is at 400 kPa and 17 C. The paddle wheel is now turned by a motor until 75 kJ:kg of work has been transferred to air. Model the air as an ideal gas with constant speci c heats 1 and calculate the amount of heat transfer per unit mass that is needed to maintain a constant air temperature while allowing the gas volume to triple.
