PREDICTION OF THE HEAT-CAPACITY OF INORGANIC MOLECULAR LIQUIDS

Analysis of the experimental data on the heat capacity of liquids enco mpassing 350 inorganic molecular liquids yielded the atomic heat capac ity fractions for 58 elements. Data are given on the precision of the heat capacity calculation using the Neumann-Kopp rule and the recommen ded atomic fractions C(p). For the Kelly rule, we established that the proportionality coefficient between the heat capacity with the number of atoms in the molecule, in the general case, depends on the type of anion and coordination of the compound. The values of the coefficient are given for halides with different coordination. The Neumann-Kopp a nd Kelly rules provide entirely satisfactory predictions of the heat c apacity of molecular inorganic liquids using the extremely available d ata on the compound studied.
