Question

For the following graph match the column I with column II.

Column-I	Column-II
(A) AB	(p) DU = 0
(B) BC	(q) DW < 0
(C) CD	(r) DW = 0
(D) DA	(s) DW > 0

• A. a® s, b ® p, c ® q, d ® r
• B. a® r, b ® s, c ® p, d ® q
• C. a®r, b ® q, c ® p, d ® s
• D. a®q, b ® p, c ® r, d ® s

Answer 1

Answer: (B)

a® r, b ® s, c ® p, d ® q

Answer 2

AB isochoric process, DW = 0

BC isobaric expansion, DW = (+) ve

CD isothermal process as

T_C = = T_D = , so DU = 0

DA isobaric compression, DW = (–) ve
