Match the following :

The correct answer is

Options

A. A - V, B - I, C - II, D - III
B. A-I, B- III, C - II, D - IV
C. A - II, B - V, C - III, D - I
D. A - II, B - V, C - I, D - III

Answer

B

Explanation

The correct match is
`II rarr A, V rarr B, III rarr C, I rarr D`.
Their explanations are as follows :
`(D) rarr I`
In an isothermal reversible expansion
`Delta T = 0`
`Delta U = C_(V) , Delta T = 0`
`(A) rarr II`
If wall is adiabatic then
`q = 0`
From first law of thermodynamics
`Delta U = q + W`
`:. Delta U = W_("adiabatic")`
`(C ) rarr III`
For thermally conducting walls
`Delta U = -q`
`(B) rarr V`
For close system
`q != 0, w != 0` and `W = -ve`
From first law of thermodynamics
`Delta U = q - W`
