Question:
Air is compressed from an initial state of 1 bar and 298.15 K to a final state of 3 bar and 298.15 K by mechanically reversible processes in a closed system:
(a) Heating at constant volume followed by cooling at constant pressure.
We assume air to be in its ideal-gas state, and assume constant heat capacities, CVig = 20.785 and CPig = 29.100 Jmol1K1. Calculate the work required, heat transferred, and the changes in internal energy and enthalpy of the air for each process. (V1ig = 0.025 m3, V2ig = 0.0083 m3)
