2.41. 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 AU and AH for the process on the basis of 1 mol of gas. Assume for the gas that PVIT is constant, Cy = (5/2)R, and Cp = (7/2)R.
