A 1.75 mole sample of carbon dioxide, for which CP,m=37.1 J K−1 mol−1 at 298 K, is expanded reversibly and adiabatically from a volume of 3.25 L and a temperature of 298 K to a final volume of 40.0 L. Calculate the final temperature, q, w, ∆U, and ∆H. Assume that carbon dioxide is an ideal gas and its CP,m is constant over the temperature interval.
