Question

Consider a pressure versus volume graph, where the different curves represent different processes done on a gas. Starting at the origin to point 1, the pressure and volume are increased to 2.500 x 103 Pa and 3.74 m3, respectively From 1 to 2, the gas expands at constant pressure to a volume of 6.74 m3. From 2 to 3, the pressure rises to 4.000 x 103 Pa. Finally, from 3 to 4, the gas expands again to 11.19 m3 Rank the curves from the most positive to the most negative amount of work done on the gas.
