##dS = \frac{1}{T} (dU - PdV)## assuming dN = 0
The Attempt at a Solution
I have actually managed to solve all 4 parts correctly, except for the fact that I solved Part d) with the Sackur-Tetrode equation rather than the thermodynamic identity.
I don't understand 1) why and 2) how I can use the identity in this scenario. Was the change in the system not quasi-static? My current understanding of the thermodynamic identity is that it can only be used during quasi-static changes where variables like T and P are well-defined.
Help is greatly appreciated!
