Three processes are performed on a gas from a state given by (p₁, V₁) to a state given by (p₂, V₂) :a) An isochoric process followed by an isobaric process,b) An isobaric process followed by an isochoric process,c) A process where pV remains constant. Compute for the three processes the work performed on the gas from the initial to the final state. These processes are assumed to be reversible. Determine the analytical results first, then give numerical values in joules. Numerical Application:

P = Po = 1 bar, V = 3 Vo, P2 = 3 Po, V = Vo = 11.
