Air is contained in a cylinder device fitted with a piston-cylinder. the piston initially rests on a set of stops, and a pressure of 200 kpa is required to move the piston. initially, the air is at 100 kpa and 238c and occupies a volume of 0.25 m3. determine the amount of heat transferred to the air, in kj, while increasing the temperature to 700 k. assume air has constant specific heats evaluated at 300 k.
