[QUOTE="Philip Koeck, post: 6195503, member: 586311"] I just quickly checked what that would give for an ideal gas (by replacing α and dP from the ideal gas law) and I get dS = n C[SUB]V[/SUB] dT / T + n R dV / V, just like it should be. Very nice! I'm wondering a bit about solids versus liquids. For liquids I can understand that entropy changes with volume since a liquid can arrange itself in more different ways if it has more space. For a solid, however, I don't see that. In a perfect crystal every atom is in its spot no matter how big the distance between atoms is. How can one explain the volume dependence of entropy then? [/QUOTE]
