Work done ON the fluid is determined by taking negative ofthe area under given curve from Point (i) to Point (f):
Work Done ONFluid For (i) ---> (f)} = -{Area Under Curve} =
\(\displaystyle=-{\left({6.0}{e}+{6}\right)}\cdot{\left({1}\right)}\pm{\left({\frac{{{1}}}{{{2}}}}\right)}\cdot{\left({6.0}{e}+{6}+{2.0}{e}+{6}\right)}\cdot{\left({1}\right)}\pm{\left({2.0}{e}+{6}\right)}\cdot{\left({1}\right)}\)
\(\displaystyle=-{1.20}{e}+{7}\) Joules
Work done ON fluid during reverse compression along same pathfrom Point (f) to Point (i) will be equal to the negative of above Item(a) result:
{Work Done ON Fluid For (f) --->(i)} = 1.20e+7 Joules

When a gas is taken from a to c along the curved path in the figure (Figure 1) , the work done by the gas is W = -40 J and the heat added to the gas is Q = -140 J . Along path abc, the work done by the gas is W = -50 J . (That is, 50 J of work is done on the gas.)
