A heat engine using a diatomic gas follows the cycle shown below. Its temperature at point 1 is 20°C. Heat energy is inputted into the heat engine during process 1-2 and is exhausted during processes 2-3 and 3-1. You may consider the gas in the heat engine an ideal gas. p (atm) 1.5 1.0- 0.5- 1 3 0+ V (cm³) 0 10 20 30 40 Determine: (i) The temperatures at point 2 and point 3. (ii) For process 1-2, the work done by the gas and AEint for the gas. For Process 1-2, the heat gained by the gas. (iii) (iv) For process 2-3, the work done by the gas and the heat loss by the gas. The engine's thermal efficiency. (v)
