please draw a sketch to complete the question

An ideal gas initially at 600K 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 (where unknown) both T and P for states 1,2 and 3. (c) Calculate Q,W,U, and H for each step of the cycle
