Question:

A 2.35 mole sample of an ideal gas, for which CV ,m = 3/2R, initially at 27.0°C and 1.75 × 106 Pa undergoes a two stage transformation. For each of the stages described in the following list, calculate the final pressure, as well as q, w, ΔU, and ΔH. Also calculate q, w, ΔU, and ΔH for the complete process. 

a. The gas is expanded isothermally and reversibly until the volume triples.

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