Assignment Help:

1 kg of air is allowed to expand reversibly in a cylinder behind a piston in such a way that the temperature remains constant at 260 degree while the volume is doubled.The piston is then move in,and heat is rejected bt the air reversibly at constant pressure until the volume is the same as it was initially.Calculate the net heat flow and the overall change of entropy.sketch the process of p-V and T-s diagram.
