Two moles of a perfect gas undergo the following process: (a) A reversible isobaric expansion from (`1.0` atm, `20.0` litre) to (`1.0` atm,`40.0`litre). (b) A reversible isochoric change of state from (`1.0` atm, `40.0` litre) to (`1.0` atm, `40.0` litre). (b) A reversible isochoric change of state from (`1.0` atm, `40.0` litre) to (`0.5` atm, `40.0` litre). (c) A reversible isothermal compression from (`0.5`atm, `40.0` litre) to (`1.0` atm, `20.0` litre). (i) Sketch with labels each of the process on the same `P-V` diagram. (ii) Calculate the total work `(W)` and the total heat change `(q)` involved in the above process. (iii) What will be the value of `DeltaU, DeltaH` and `DeltaS` for the overall process?
