One more of an ideal gas initially at 27oC and 1 bar pressure is heated and allowed to expand reversibly at a constant pressure until the final temperature is 327oC. For this gas, Cv,m = 2.5R, constant over the temperature range. (Note from SRB: Cv,m is the molar heat capacity. An earlier version of the 5th edition that I used last year used Cv with a bar over it, as we have been doing in class. Sorry for any confusion.)....
