The difference between the specific heats at constant pressure and volume is described by the expression where
Question:
where αv is the volume coefficient of thermal expansion, v0 is the specific volume (i.e., volume per unit mass, or the reciprocal of density), β is the compressibility, and T is the absolute temperature. Compute the values of cv at room temperature (293 K) for copper and nickel using the data in Table 19.1, assuming that αv = 3αl and given that the values of β for Cu and Ni are 8.35 × 10-12 and 5.51 × 10-12 (Pa)-1, respectively.
