Physics

An engine that operates by means of an ideal diatomic ideal gasin a piston with 2.70 moles of gas. The gas starts at point A with3x103 Pa of pressure and 2.5x10-2 m3. To get from B from A, it isexpanded by an isobaric process to double the initial volume. FromB to C it expands adiabatically until it reaches three times thevolume in A. From C to D the pressure decreases without changingthe volume and from D to A it is an isothermal compression. a) Drawthe PV diagram of the process and determine the pressure and volumeat each vertex. Calculate: b) full cycle work. C) The heattransferred in each process. D) The real efficiency and efficiencyof carnot. D) The change of entropy in each process.
Forgive me, I'm a little bit vague on the detail.
