Consider 1.50 mol of a monoatomic ideal gas (Cv,m = 3/2R) that is initially at 390.K (taken as 3 significant figures) and 2.20 atm pressure. For this system, calculate the change in entropy (ΔS), the change in internal energy (ΔU), and the change in enthalpy (ΔH) for a reversible adiabatic expansion of this gas to a final pressure of 1.10 atm. Also calculate the final temperature (T) and volume (V).
