Question

For the given cyclic process $CAB$ as shown for a gas, the work done is :

• A. 1 J
• B. 5 J
• C. 10 J
• D. 30 J

Answer 1

Answer: (C)

Since P-V indicator diagram is given, so work done by gas is area under the cyclic diagram.
$\therefore \Delta W=$ Work done by gas $=\frac{1}{2}\times 4\times 5J$
$=10J$
