Unformatted text preview: in a mechanically reversible process to 40 ° C if the heat capacity of the piston and cylinder is neglected? 2. An ideal gas initially at 600 K and 10 bar undergoes a four-step mechanically reversible cycle in a closed system. Take C P = (7/2)R and C V = (5/2)R. (1 → 2) Isothermal expansion to 3 bar (2 → 3) Pressure decreases to 2 bar at constant volume (3 → 4) Volume decreases at constant pressure (4 → 1) Adiabatically compression to 10 bar (back to its initial state) (a) Sketch the cycle on a PV diagram. (b) Determine both T and P for states 1, 2, 3, & 4. (c) Calculate Q , W , ∆ U , and ∆ H (J/mol) for each step of the cycle....
