Expression for cp-cv
WebJan 16, 2024 · Cp − CV = TVα2 κT And this is a completely general result since the only assumptions made were those that allowed us to use the combined first and second laws in the form dU = TdS– pdV. That means that this expression can be applied to any substance whether gas, liquid, animal, vegetable, or mineral. But what is the result for an ideal gas? WebStarting from the expression C p − C V = T(∂p/∂T) V (∂V/∂T) p, use the appropriate relations between partial derivatives to show that . ... Show that for an ideal gas cp = cv + R u. Q: Starting from the expression of the total energy carried by the lattice; Q: What is a personal balance sheet? Name three classifications of assets. Briefly

WebAug 9, 2024 · 1 Answer. You could start with C V = ( ∂ U / ∂ T) V = T ( ∂ S / ∂ T) V and H and p instead of U and V for C p as appropriate. Then generate an expansion for S as d S = ( ∂ S / ∂ V) T d V + ( ∂ S / ∂ T) V d T and differentiate wrt T. You should then get an expression in C V and C p plus other terms that you can find using the vdw ...
