Question

A cyclic process is shown in the figure. Work done during the cyclic process ABCDA is

• A. 1600 J
• B. 150 J
• C. 600 J
• D. 900 J

Answer 1

The correct option is B 150 J

The area under $P-V$ curve gives the work done,

Since it is a cyclic process W.B will be the area enclosed by $ABCD$.

Area $=W.D.=1\times (1\times {10}^2)+\frac{1}{2}\times 1\times (1\times {10}^2)$

$=150J$
