A piston-cylinder device contains carbon monoxide gas at 100 kPa and 27C. a) In process A, the gas is heated at constant volume until the pressure is doubled. It is then expanded under pressure constant until the volume triples its initial value b) In process B, the same gas in the initial state is first expanded at constant pressure until it triples the volume; a The gas is then heated at constant volume until it reaches the same final pressure as in process A. Determine the net heat transferred in these two processes, the net work, and the internal energy changes in kJ/kg.
