Hi,
As is commonly known,
u = u(T,v)
h = u(T,p)
I've worked with some maths proofs of this a while ago, but do you guys have an intuitive way of understanding this without the maths, that is, why the state function for internal energy is defined by intensive volume and enthalpy with pressure?
I seem to recall, I used the model for thought, that if a system had a moving boundary, as in the case of a changing enthalpy, then the volume would not stay constant, so we could not use the constant volume specific heat capacity, so we used specific pressure, but I feel like a new way of thinking about it is required for me..
