The conditions of a gas change in a steady flow process from 20 degrees C and 1000 kPa to 60 degrees C and 100 kPa. Devise a reversible nonflow process (any number of steps) for accomplishing this change of state, and calculate delta U and delta 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.
