I think I'm following, but if I change the temperature in the first step, how can I go about calculating the work since I don't know anything about temperature?
Given what you've said for the first step w does not = 0. Is that correct?
Here is my work for part b,
The first leg in this parcels journey is expansion under constant pressure to α2.
So . . .
∫ dw = ∫ pdα with the limits of integration being α1 up to α2.
w = p (α2 - α1) I used the equation of state to substitute for α. Rd is written simply as...

Problem: A sample of dry air has an initial pressure p1 = 1000 hPa and temperature T1 = 300K. It undergoes a process that takes it to a new pressure p2 = 500 hPa with unchanged temperature T2 = T1. Compute the mechanical work per unit mass perfromed by the sample under the...
