Question

# Let's imagine that we have an amazing device that we can use to adjust the pressure and volume of a sample chamber however we want. We use this amazing system

to create the pressure-volume curve shown in the image attached to this question. The green part of the pressure-volume curve represents a semicircle where the maximum is a point that corresponds to the average volume and a pressure of P2 = 2P. At V1 and V2 the system is at a pressure P1 = P. If the pressure is the same at the end of the process as at the beginning, is work done in the process in expanding from V1 to V2? O A) yes O B) no 09-P(V2 – V1) –- xP² \text { ĐD) } P\left(V_{2}-V_{1}\right)+\frac{1}{2} \pi P^{2} \text { ○C) }-P\left(V_{2}-V_{1}\right)-\frac{1}{2} \pi P^{2} \text { ĐE) }-P\left(V_{2}-V_{1}\right)-\frac{1}{2} \pi(2 P)^{2} \text { OF) } \mathrm{P}\left(\mathrm{V}_{2}-\mathrm{V}_{1}\right) G) None of the above
