Question:

Which one of the following options is the correct combination?

(III)(ii)(S)

(II)(iv)(P)

(II)(iv)(R)

(IV)(ii)(S)

Solution:

I: Work done by adiabatic process: W = (P₂V₂ - P₁V₁)/(γ - 1)
II: Work done by isobaric process: W = -P₂V₂ + PV₁ = PΔV
III : Work done by isochoric Process : W = 0. As the volume is constant throughout the process.
IV: Work done by isothermal : W = -nRT ln(V₂/V₁)
