Question

In above shown figure, calculate the total work done on the gas when it is transformed from state a to state c, along the path indicated?

• A. 1,500 J
• B. 3,000 J
• C. 4,500 J
• D. 5,000 J
• E. 9,500 J

Answer 1

Answer: (C)

4,500 J

The thermodynamic work done is $W=PdV$

As $dV=0$ for path b to c so it will not contribute any work.

The work done will come from path a to b and the required work done,

$W=(3\times {10}^5)\times (25-10){10}^{-3}=4500J$
