1. The problem statement, all variables and given/known data One mole of an ideal gas at an inital tempreature of 300K and pressure of 4 atm is carried through the following reversible cycle: a) It expands isothermally until its volume is doubled. b) It is compressed to its original volume at constant pressure. c) It is compressed isothermally to a pressure of 4 atm. d) It expands at constant pressure to its original volume Make a plot of this cycle process on a PV diagram and calculate the work done by the gas per cycle. 2. Relevant equations 3. The attempt at a solution Okay so step a. means that while Vo goes to 2Vo the pressure doubles as well, yes? And step b means that the pressure is the same but the volume goes to Vo. And so then step C should mean that since P is returning to its initial, the gas returns to Vo too, right? But if that's true, then D doesn't make sense since it has already returned to Vo. Please help! Once I get the diagram correct, I'm just going to use the area to find the work done.
