Abstract

The Pippard relations (C_P vs. a_P and a_P vs. k_T) are examined
at various temperatures up to 1200 K at zero pressure (P = 0) for the cubic
gauche nitrogen. The specific heat (C_P) is related to the thermal
expansion (a_P) and
the a_P is
also related to the isothermal compressibility (k_T) as
the Pippard relations for this solid structure. For those relations,
experimental data are used from the literature. It is found that the variation
of the C_P with the a_P and a_P with the
k_T is
linear. Using the linear relations dP/dT is predicted, which can be compared
with the experimental measurements in the P – T phase diagram of cubic gauche
nitrogen.
