The conditions of a gas change in a steady-flow process from 20 °C and 1000 kPa to 60 °C and 100 kPa. Devise a reversible non-flow 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.
