The conditions of a gas change in a steady-flow process from 293.15 K (20°C) and 1000 kPa to 333.15 K (60°C) and 100 kPa. Devise a reversible nonflow process (any number of steps) for accomplishing this change of state, and calculate U and H for the process on the basis of 1 mol of gas. Assume for the gas that PV/T is constant, Cv = (5/2)R, and Cp = (7/2)R
