For a material given by U=C1PV2 and PV2=C2T
Find the entropy
dS/dU = 1/T; dU/dV = -P
I don't know if I require anything else
The Attempt at a Solution
So from 2 equations I got U = C1
But dU/dT is not equal to S. Which equation do I use to get the entropy? I was thinking of using F = U-TS. Which will give F = C1PV2 - TS And then doing dF/dT but then I didn't use the 2nd condition at all.
What am I missing?
