## Homework Statement

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.]

## Homework Equations

## 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)
