Calculate ΔU, ΔΗ, Q and W for 1 kg of air that undergoes the following mechanically reversible process: Isobaric heating from 300 K and 1bar until the three times the initial volume. Make the assumption that that PV/T=83.14 (bar-cm3 )/(mole-K) and the CP for air is 29 Joule/(mole-K) and the molecular weight of air is 28.9 g/mole.
