Question 1 [10 marks]: An engineer proposes a simple three step cycle that is to be executed within a gas-filled closed- cylinder system. The three steps in order are: 1 = 2 Isobaric expansion 2 = 3 Isothermal expansion 3 = 1 Adiabatic compression Does this form a closed cycle? Explain your answer with the aid of diagrams.
