In a reversible isochoric change

Two moles of an ideal gas undergo the following process : (a) a reversible isobaric expansion from ( P atm, V L) to ( P atm , 2V L) . (b) a reversible isochoric change of state from ( P atm , 2V,L) to (P//2 atm, 2V L) (c ) a reversible isothermal compression from (P//2 atm, 2V L) to (P atm, V L) . Sketch with labels each of the processes on the same P-V diagram.
