To establish the positivity of the specific heat at constant pressure Cp compressibility coefficient at constant temperature κT (see relations (6.31)), follow the steps given here [65]:a) Show that the Mayer relation (5.42) can be recast as,where α is the thermal coefficient of expansion,

b) Show that

c) Conclude from these two results that κT ≥ 0 and Cp ≥ 0.
