Question

An ideal gas, Cp = (5/2)R and Cv = (3/2)R, is changed from P = 1 bar and
V{ = 12 m3 to P2 = 12 bar and V2 = 1 m3 by the following mechanically reversible
processes:
(a) Isothermal compression.
(b) Adiabatic compression followed by cooling at constant pressure.
(c) Adiabatic compression followed by cooling at constant volume.
(d) Heating at constant volume followed by cooling at constant pressure.
(e) Cooling at constant pressure followed by heating at constant volume.
Calculate Q, W, ∆U, and ∆H for each of these processes, and sketch the paths of all
processes on a single P V diagram.
