Suppose 0.50 mol of a monoatomic ideal gas is changed from state A to state D by one of the processes shown on the PV diagram of the figure below.

(This is my edited version of the image)

(a) Find the total work done by the gas if it follows the constant pressure path A-E followed by the constant temperature path E-D.

(b) Calculate the total change in internal energy of the gas during the entire process and the total heat flow into the gas.

I'm having trouble with (a). Is the work done from path A-E, E-D reflected on the first diagram I made, or the second? I guess I'm confused as to whether I'm supposed to use 1 or 2 atm in my calculations. thanks
