Cp -> Cv conversion for metals

  1. Dec 1, 2005 #1
    Can someone please remind me how to convert values of Heat capacaty at constant pressure to heat capacity at constant volume? I beleive it has something to do with the volume expansivity (1/V)*(dV/dT) at constant pressure, but I can't find my therm textbook and I can't remember how to proceed.

    Here are some useful relations:

    [tex]\frac{du}{dT}= C_v (T)[/tex]

    [tex]\frac{dh}{dT}= C_p (T)[/tex]

    [tex]h = u + Pv[/tex]
