Match List - I with List - II. List - I (A) Isobaric (B) Isochoric (C) Adiabatic (D) Isothermal ΔQ = Heat supplied ΔW = Work done by the system ΔU = Change in internal energy P = Pressure of the system ΔV = Change in volume of the system Choose the correct Ans. from the options given below :

1. (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
2. (A)-(II), (B)-(IV), (C)-(III), (D)-(I)
3. (A)-(IV), (B)-(II), (C)-(III), (D)-(I)
4. (A)-(IV), (B)-(I), (C)-(III), (D)-(II)

Correct answer: (A)-(IV), (B)-(II), (C)-(III), (D)-(I)

Solution

The correct matches align with the definitions of thermodynamic processes: Isobaric (constant pressure) corresponds to ΔQ = ΔU + ΔW, Isothermal (constant temperature) relates to ΔQ = ΔW, Isochoric (constant volume) means ΔQ = ΔU, and Adiabatic (no heat exchange) is characterized by ΔU = -ΔW.
