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:

$$\frac{du}{dT}= C_v (T)$$

$$\frac{dh}{dT}= C_p (T)$$

$$h = u + Pv$$
