Cv and Cp
Do we see a difference in Cv and Cp with liquids and solids or is water the only exception to Cv and Cp staying the same?

Re: Cv and Cp
As far as I'm aware, Cv and Cp in solids and liquids do not differ much and thus do not have much of a difference. In gases, however, Cv and Cp do differ. Hope this helps! :)

Re: Cv and Cp
C_v and C_p won't differ much just because changing their volume and pressure is super hard (ie: solids and liquids basically have a constant pressure and volume when given the same number of moles). You can't say the same for gases because the particles aren't bounded and therefore can expand or contract depending on temp, which changes either pressure or temperature (think of PV=nRT and manipulating T).

Re: Cv and Cp
Cv and Cp should stay relatively similar (small enough that it doesn't have a significant impact on the calculations) in liquids and solids as they have bonds holding them together in a single form. All gasses are unbound and free to move around the space provided, thus requiring the clarification of Cp and Cv.

Re: Cv and Cp
The Cv and Cp relate to a change in gases, I do not think it relates to a change in liquids or solids!

Re: Cv and Cp
Solids and liquids are not easily compressible like gases, and therefore Cv and Cp are approximately equal. With gases, however, easy compressibility allows for significant changes in volume due to pressure changes.
