0.0200 m3/mol of air at 10 bar (300 K) has expanded by reduction of pressure to 5 bar (300 K) by two mechanically reversible process – heating at constant pressure followed by cooling at constant volume. Calculate the heat and work requirements and ∆U and ∆H of the air for each path (expressed in J/mol). Use the following heat capacities for air: CV = 20.78 J/mol·K and Cp = 29.10 J/mol·K. Assume also for air that PV/T is constant, regardless of the changes it undergoes.
