A diatomic ideal gas originally at pressure Po and volume Vo is heated at
constant volume until its pressure increases by a factor of 3. Next it is
isothermally expanded until its pressure returns to Po. Finally it is
isobarically compressed to its initial volume.
a) Show the process on a PV diagram.
b) Find Q, W, and delta E for each of the 3 legs [All entries should be in terms of the “givens”—
Po and Vo.]
The Attempt at a Solution
Part A) Note the very crude attachment.
Part B) I think i have this generaly correct, but im having trouble using the given terms
Leg 1 (AB)
Q = E = nC_v(delta T), W = 0
Leg 2 (BC)
Q = W, E = 0
Leg 3 (CA)
Q = E + W, W = P(delta V)
