The nitrogen is now compressed to a final pressure of 500 kPa. During the process, heat is transferred from the nitrogen such that the temperature inside the cylinder remains constant. Calculate: a) The initial and final air volume, m'. b) The work input during this process, kJ. d) The heat transfer during this process, kJ. e) Show the compression process on P-V diagram
