Melting Heats of Compounds

The melting heats AZZm for binary inorganic compounds are presented in Table 9.1, for elements in Table 9.3. Melting heats of organic and organometallic crystals with molecular structures are much smaller. Thus, AH (kJ/mol) = 5.4 for cyclobutane,

Knowing the melting energy, one can estimate the extent of the short-range order in liquids. Let us suppose that solid ZnS, NaCl and CsCl (to take representative examples) are being split into cubic blocks of diminishing size and calculate the
