A piston-cylinder device has a ring to limit the expansion stroke. Initially, the mass of air is 2 kg at 500 kPa, 30oC. Heat is now transferred until the piston touches the stop, at which point the volume is twice the original volume. More heat is transferred until the pressure inside also doubles. Using the IG model, determine.
(a) The amount of heat transfer.
(b) The final temperature.
