Match List-I with List-II. List-I: (A) Isothermal, (B) Adiabatic, (C) Isobaric, (D) Isochoric. List-II: (I) ΔW = 0, (II) ΔQ = 0, (III) ΔU ≠ 0, (IV) ΔU = 0. Choose the correct match.

G1 Physics · Accepted Answer

For an ideal gas: Isothermal process: ΔT=0, so ΔU=0 ⇒ A–IV. Adiabatic process: ΔQ=0 ⇒ B–II. Isobaric process generally changes temperature, so ΔU≠0 ⇒ C–III. Isochoric process: ΔV=0, so work ΔW=PΔV=0 ⇒ D–I. Thus A–IV, B–II, C–III, D–I. Correct option: C.
