The molar heat capacity of the gas at constant volume, Cv, is 3/2R and is independent of temperature. Calculate the work done, the heat absorbed, and the change in U and H for the gas if the process is carried out (1) isothermally and reversibly, and (2) adiabatically and reversibly.

28 moles of an ideal gas with a molar specific heat at constant volume of cv=3.2R is initially in state "A" at pressure 73390 Pa and volume 1.0 m3. The gas then expands isobarically to state "B" which has volume 2.6?3m3. The gas then cools isochorically to state "C". The gas finally returns from state "C" to "A" via an isothermal process. What is the adiabatic constant γ for this gas? What is Q during the expansion from "A" to...
