Consider a pressure versus volume graph, where the different curves represent different processes done on a gas. Starting at the origin to point 1,1, the pressure and volume are increased to 2795Pa2795Pa and 4.08m3,4.08m3, respectively. From 11 to 2,2, the gas expands at constant pressure to a volume of 7.08m3.7.08m3. From 22 to 3,3, the pressure rises to 4164Pa.4164Pa. Finally, from 33 to 4,4, the gas expands again to11.70m3.11.70m3.

Rank the curves from the most positive to the most negative amount of work done on thegas.
