Answer to Question #11567 in Molecular Physics | Thermodynamics for Lee Zhen Yueng

Question

A certain fluid at 10 bar is contained in a cylinder behind a piston, the initial volume
being 0.05 m^3. Calculate the work done by the fluid when it expands reversibly:
i. at constant pressure to a final volume of 0.2 m^3
ii. according to a linear law to a final volume of 0.2 m^3 and a final pressure of 2 bar
iii. according to a law pV = constant to a final volume of 0.1 m^3
iv. according to a law pV^3 = constant to a final volume 0f 0.06 m^3
v. according to a law p=(a/v^2) - (b/v) to a final volume of 0.1 m^3 and a final pressure of 1 bar
where A and B are constants.
Sketch all processes on a p-V diagram.

I have the answer but I need the solution. Thanks
