Solution


Q.

Match List I with List II

  List I   List II
(A) Isobaric (I) △Q=△W
(B) Isochoric (II) △Q=△U
(C) Adiabatic (III) △Q=zero
(D) Isothermal (IV) △Q=△U+P△V

 

△Q = Heat supplied

△W = Work done by the system

△U = Change in internal energy

P = Pressure of the system

△V = Change in volume of the system

Choose the correct answer from the options given below:         [2025]
1 (A)-(IV), (B)-(III), (C)-(II), (D)-(I)  
2 (A)-(IV), (B)-(I), (C)-(III), (D)-(II)  
3 (A)-(IV), (B)-(II), (C)-(III), (D)-(I)  
4 (A)-(II), (B)-(IV), (C)-(III), (D)-(I)  

Ans.

(3)

(A) Isobaric process, △Q=△U+P△V

(B) Isochoric process, △Q=△U

(C) Adiabatic process, △Q=0

(D) Isothermal process, (△U=0), △Q=△W
