Consider 1.00 mol of argon (Ar), an ideal monatomic gas (CV,m = 12.47 J/mol.K) at an initial temperature and pressure T = 300.0 K and p = 5.00 atm. Find q, w, ?U, and ?H for each of the following processes.
a) The gas is expanded isothermally and reversibly to a final pressure pf = 2.00 atm.
b) The gas is expanded isothermally and irreversibly against a constant pressure equal to the final pressure, pex = pf = 2.00 atm.
c) The gas is heated reversibly at constant pressure to a final temperature Tf = 360.0 K.
