A particular thermodynamic cycle acting on a monatomic ideal gas (y = 1.67) includes an isobaric expansion, an isochoric cooling, and then a
isothermic contraction. The PV diagram is shown in the image below.
P
V
The isobaric expansion occurs at a pressure of 1.8 × 105 Pa and changes the volume of the gas from 6.7 x 10-2 m³ to 13.08 × 102m³.
What is the efficiency of the process?
