Homework Statement
A heat engine uses 2 mole of a diatomic gas that follows the pV cycle shown, how much work is done, over the cycle if P=100kPa, T1=207K
* P is suppose to be 0.5P this was a typo on the graph
This is what I've figured out so far: (if i am incorrect on anything please let me know)
W1→2 = 0
W2→3=nRΔT
So it would look like:
(2)(5/2)(8.31)(?-207)
The problem is i can't figure out how to find the other tempurature
W3→1=nRTln(v2/v1)
So it would look like this
(2)(8.31)(207)ln(?/?)
I don't understand how to get the volumes in this problem all the other problems i have had have given me a volume.
