Question

Following graph shows a single strange expansion process, then work done by the system is :

• A. $-9104J$
• B. $-202.6J$
• C. $-506J$
• D. $-101.3J$

Answer 1

The correct option is B $-202.6J$

At constant pressure

$W=P\left(△V\right)$

$1atm(2-4)lit$

$-2\times 1.013\times {10}^{5}pa\times 1000\times 106-6\left(e{n}^3\right)$

$-202.6j$
