1. The problem statement, all variables and given/known data A monatomic gas at 27degrees C undergoes a constant volume process from A to B and a constant pressure process from B to C, as shown in the figure below: Find the total work done during these two processes. 2. Relevant equations Not sure... 3. The attempt at a solution I know I have to find the area under the curve, but I'm not sure how I have to relate the ATM's (pressure) to volume.
