Q3: Air at 15°C and 1.05 bar occupies 0.02 m³. The air is heated at constant volume until the pressure is 4.2 bar, and then cooled at a constant pressure until the temperature become 250°C. Sketch the T-S diagram for the processes and calculate the net heat supplied to or from the air and the net of entropy change, Assume air to be a perfect gas.
