U = Q + W
The Attempt at a Solution
I don't understand why there is no work done on gas from Q to R. I thought that work done on gas = pv?
If so, then why there is no work done on gas because there is increase in pressure?
So, I tried to find a reason, and I thought that work done should be the area under the graph, because it is a volume against pressure graph. In this case, then there shouldn't be any work done from P to Q too because the change is a straight line. But there is. There is a work done of +240J.
Can someone explain to me where I'm wrong? Thanks
