The accompanying pressure-volume graph shows an engine cycle with one isothermal process, B-C. The working substance is an ideal gas. At point B, the pressure is 3.20×105 Pa and the volume is 0.0480 m3. At point C, the pressure is 2.10×105 Pa and the volume is 0.0730 m3. At point A the volume is 0.0230 m3. What is the net work done by the gas during one cycle?
