Match the thermodynamic processes in List-I with the corresponding conditions in List-II: List-I (A) Isothermal (B) Isochoric (C) Adiabatic (D) Isobaric List-II (i) Pressure remains unchanged (ii) Temperature remains unchanged (iii) Volume remains unchanged (iv) Heat content remains unchanged Select the correct matching from the choices below:

1. (A) → (i), (B) → (iii), (C) → (ii), (D) → (iv)
2. (A) → (ii), (B) → (iii), (C) → (iv), (D) → (i)
3. (A) → (ii), (B) → (iv), (C) → (iii), (D) → (i)
4. (A) → (iii), (B) → (ii), (C) → (i), (D) → (iv)

Correct answer: (A) → (ii), (B) → (iv), (C) → (iii), (D) → (i)

Solution

The correct option matches each thermodynamic process with its defining characteristic: isothermal processes maintain constant temperature, isochoric processes keep volume constant, adiabatic processes do not exchange heat (thus heat content changes), and isobaric processes maintain constant pressure.
