Description of Condensed-Phase Data Format

    where Heat Capacity is defined as:     Cp(T) = a + bT + cT2 + d/T2
Select (click) Radio Button to highlight item in example data box below.
Line 1 Name of Species
Line 2 Format     No. of Cp(T) Parameter Sets     Stoichiometry **
Line 3 Heat of Formation * (Joules/mol) Absolute Entropy * (Joules/mol-K)
Line 4 Transition Temp.1 (K) Heat Capacity Coefficients (from T=298 to Trans.Temp.1)
Line 5 Heat of Transition (Joules/mol)
Line 6 Transition Temp.2 (K) Heat Capacity Coefficients (from T=Trans.Temp.1 to Trans.Temp.2)
Line 7 Heat of Transition (Joules/mol)
Line 8 Maximum T (K) Heat Capacity Coefficients (from T=Trans.Temp.2 to Max.T)
    * at 298K       ** Stoichiometry for each element in the system; in this case, Na-Al-B-Si-O.

    Note: Example has two (2) transition temperature entries, is from the Na-Al-B-Si-O system.
