Mr Luda wants to understand further about a newly created gas. The gas is initially at a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1). The gas undergoes a 3-step process in which it is first compressed isothermally to a pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constant pressure back to its original volume (State 3). Finally, the gas is returned to its original State 1 by cooling at constant volume. a) Sketch the cycle of this system on a P – V diagram. b) Calculate the work done (in kJ) for each process step. c) Determine the total work done for the three-process cycle. d) State whether the work done is on or by the system.

Question
Mr Luda wants to understand further about a newly created gas. The gas is initially
at a pressure of 90 kPa, volume of 1.258 m3 and temperature of 10°C (State 1).
The gas undergoes a 3-step process in which it is first compressed isothermally to
a pressure of 400 kPa and volume of 0.283 m3 (State 2), then expanded at constant
pressure back to its original volume (State 3). Finally, the gas is returned to its
original State 1 by cooling at constant volume.
a) Sketch the cycle of this system on a P – V diagram.
b) Calculate the work done (in kJ) for each process step.
c) Determine the total work done for the three-process cycle.
d) State whether the work done is on or by the system.
