The initial pressure is 3 bar, the initial volume is 0.1 m3, and the final volume is 0.2 m3. The change
in specific internal energy of the gas in the process is u2-ul = -55 kJ/kg.
There are no significant changes in kinetic or potential energy.
a) Sketch the process on a p-V diagram
b) Calculatę the work done by the piston, in kJ.
c) Determine the net heat transfer for the process, in kJ.
