1kg of a fluid is contained in a cylinder at an initial pressure of 20bar. The fluid is allowed to expand reversibly behind a piston according to the c = pv² until the volume is doubled. The
fuid is then cooled reversibly at constant pressure until the volume is doubled. The fluid is
then cooled reversibly at a constant pressure until the piston regains its original position heat
is then supplied reversibly with the piston firmly locked in position until the pressure rises to
the original value of 20bar. Calculate the networkdone by the fluid, for an initial volume of
0.05m³.​
