Q.

Match List-I with List-II

  List-I   List-II
(A) Isothermal (I) △W (work done) = 0
(B) Adiabatic (II) △Q (supplied heat) = 0
(C) Isobaric (III) △U (change in internal energy) ≠ 0
(D) Isochoric (IV) △U=0

 

Choose the correct answer from the options given below:          [2025]

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

Ans.

(3)

For Isothermal,

T = constant, △T=0, △U=nCv△T=0          ... (IV)

For Adiabatic,

△Q=0          ... (II)

For Isobaric,

p = constant, △U=nCv△T≠0,

△Q≠0, △W≠0          ... (III)

For Isochoric,

V = constant, △W=0          ... (I)
