Question

Match List-I with List-II:

List-I (Process)	List-II (Characteristic)
(A) Adiabatic	(I) No volume change takes place
(B) Isochoric	(II) No pressure change takes place
(C) Isobaric	(III) No temperature change takes place
(D) Isothermal	(IV) No heat transfer takes place

Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (II), (D) - (I)
• (A) - (II), (B) - (I), (C) - (IV), (D) - (III)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)
• (A) - (IV), (B) - (I), (C) - (II), (D) - (III)

Hint:

The iso prefix tells you which quantity stays constant in each of the four processes.

Answer 1

The Correct Option is D

Step 1: Go through each thermodynamic process definition one at a time. Adiabatic process means no heat is allowed to enter or leave the system during the process, so it matches characteristic (IV), no heat transfer takes place.
Step 2: Isochoric process means the volume of the system stays fixed throughout, so it matches characteristic (I), no volume change takes place.
Step 3: Isobaric process means the pressure stays fixed throughout, so it matches characteristic (II), no pressure change takes place.
Step 4: Isothermal process means the temperature stays fixed throughout, so it matches characteristic (III), no temperature change takes place.
Step 5: Putting these together gives (A)-(IV), (B)-(I), (C)-(II), (D)-(III), exactly the pairing listed in the matching option.
