Starting at the origin to point 1, the pressure and volume are increased to 2677 Pa and 4.42 m respectively. From 1 to 2 the gas expands at constant pressure to a volume of 7.42 m3 From 2 to 3 the pressure rises to 4082 Pa. And finally from 3 to 4 the gas expands again to 11.87 m Using the ranking module, rank the curves from the most positive to the most negative amount of work done on the gas. Most Positive Work Most Negative Work 12 134 23 What is the total work done on the gas?

Work done can be found from the PV graph by calculating the area under curve
0-1:
W = area of triangle=0.5*2677*4.42
W=5916.17 J
1-2:
W= area of rectangle =2677*(7.42-4.42)
W=8031 J
2-3:
W=0 {since area is zero}
3-4:
W= area of rectangle =4082*(11.87-7.42)
W=18164.9 J
Arranging from most positive to most negative:
3-4 , 1-2 , 0-1 , 2-3
Total work done is the sum of individual work done
W=32112.07 J
