Question: An ideal gas initially at 600 K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. In step 12, pressure decreases

An ideal gas initially at 600 K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. In step 12, pressure decreases isothermally to 3 bar; in step 23, pressure decreases at constant volume to 2 bar; in step 34, volume decreases at constant pressure: and in step 41, the gas returns adiabatically to its initial state. Take CP = (7/2) R and CV = (5/2)R.
(a) Sketch the cycle on a PV diagram.
(b) Determine (w here unknown I both 7 and P for slates 1, 2, 3, and 4.
(c) Calculate Q, W, (C. and AH for each step of the cycle.
