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) → (iii), (C) → (iv), (D) → (i)

Solution

Isothermal keeps temperature constant (ii), isochoric keeps volume constant (iii), adiabatic exchanges no heat (iv), and isobaric keeps pressure constant (i): A->ii, B->iii, C->iv, D->i.
