Ok, I think I figured it out, from my previous post (sorry- I am still getting used to using the tools for math on this board) I replace the vanderwaals eqn into P in my partial p and then just solve from there.
I think so..
\Pit = \partialu/\partialv for constant t
= ( 1/\partialv\times(Tds - pdv) )
= T \times (\partialp/\partialt) - p
I think that's right. I still don't know how to get from that Maxwell relation to the ideal gas and Van der Waals eqn, though.
Like in the other problem I posted- This is the other question that I missed and just can't find a solution for.
Homework Statement
Prove the internal pressure is 0 for an ideal gas and ((n^2)a)/(v^2) for a Van der Waals gas.
Homework Equations
1. VdQ Eqn: p= (nRT)/(v-b) -...
I've been working on this proof, and I just can't get it backwards or forwards, so I must be going about it wrong or missing something. I'm on a re-do for the homework, because my first attempt was completely wrong, so here I go with the second.
Any guidance would be appreciated.
