Q3: 1kg of air can expand reversibly in cylinder behind a piston in such a way that the temperature remains constant at 260 °C while the volume is doubled. The piston is then moved in and heat is rejected by the air reversibly at constant pressure until the volume is the same as it was initially. Calculate the overall change entropy take CP=1.005 KJ/Kg.k, R=0.287 KJ/Kg.k.
