Unformatted text preview: We let the pressure drop to 101.3lkpa by brieﬂy opening the container. After resealing we heat back to 25C and arrive at 104kpa. Determine c P assuming an ideal gas and reversible and adiabatic exchanges where appropriate. 3. (6 points) This problem was on midterm 2, 2008 Assume a gas can be described by the following virial equation pV NRT = 1 + Bp + Cp 2 with B =2 . 9 × 109 1 mole Pa and C = 2 . 1 × 1016 1 Pa mole 2 . (a) Calculate the work required (for one mole at 370 K) to increase the pressure from 150 to 400 kpa. (b) Calculate the volumes for the beginning and ﬁnal state of part (a). (c) Redo part (a) assuming an ideal gas....
