1. The state of an ideal gas with CP=(5/2)R is changed from P=1 bar and V1t=12m3 to P2=12 bar and V2t=1m3 by the following mechanically reversible processes: (a) Isothermal compression. (b) Adiabatic compression followed by cooling at constant pressure. (c) Adiabatic compression followed by cooling at constant volume. (d) Heating at constant yolume followed by cooling at constant pressure. (e) Cooling at constant pressure followed by heating at constant volume. Calculate Q,W,Ut, and H for each of these processes, and sketch the paths of all processes on a single PV diagram
