The question is as follows:(adsbygoogle = window.adsbygoogle || []).push({});

the partial derivative (given as a partial, but i dont know the notation, so letter d is really little delta for the partial)

(du/dT)p = Cp - P(Beta)v

where Beta = expansivity coefficient = 1/v (dv/dT)p

again, all the "d's" are lowercase delta's for the partial derrivatives, and the "p's" next to the partials and the one with the Cp are to signify that pressure is constant.

I know i need to start with enthalpy, dh, but im pretty much stuck. if someone would point me in the right direction i would be much obliged. thanks
