Hello.(adsbygoogle = window.adsbygoogle || []).push({});

I'm having troubles solving the enthalpy for an ideal gas.

From the equation H=U+PV, i could find H substituting PV=NRT = U/c, but then i need the energy as a function of S and P, so i'd get H as a function of its proper variables (S and P)..

I can't find such an expression. It's just so easy to find the helmholtz and gibbs representation for ideal gases that i find it odd that this one gives me so much trouble. Wikipedia gives the equation for the enthalpy, but i have no clue how to write it that way :S

could anyone give me some clues to solve this one?

thanks
