5.A 3.5 mole sample of an ideal gas, for which 6138308b54aca.jpg = 3R / 2, initially at 25℃ and 1.6x106 Pa, under goes a two-stage transformation. For each of the stages described in the following list, calculate the final pressure, as well as q, w, ∆U , and ∆H . Also calculate q, w, ∆U , and ∆H for the complete process.

(b) Beginning at the end of the first stage, the temperature is raised to 105°C at constant volume.
