Question

A gas is taken through the cycle $A\to B\to C\to A$ as shown. What is the net work done by the gas:

• A. 2000 J
• B. 800 J
• C. Zero
• D. 3000 J

Answer 1

The correct option is B 800 J

Net work done by the Gas = Area under P.V graph
$W_{net}=\frac{1}{2}\times AC\times BC{W}_{net}=\frac{1}{2}\times 4\times {10}^{-3}\times 4\times {10}^5=800J$
