A gas having a mass of 9 kg is contained within a piston-cylinder machine. The gas undergoes a process for which PV1.2= Constant. The initial pressure is 2 bar and volume is 0.5m3 and the final volume is 1 m3. The specific internal energy of the gas decreases by 6 kJ/kg. Determine the net heat transfer (kJ) for this process.
Enter numerical value using the virtual keypad. Round off where necessary.
