Missing Boiling Points
The boiling point is the temperature
at which boiling occurs under a pressure of one bar.
Typical units given include degrees
Kelvin and degrees
Celsius. Because
it depends on the pressure, this is often also given, as shown in
these examples.
Missing Melting Points
The melting point is the temperature at which a compound melts. Typical units given include degrees
Kelvin and degrees
Celsius. It is
often found for organic chemicals as part of their unique characterization. Check out
these examples.
Missing Mass
Missing Solubility
The solubility
of a compound is always in some solvent and depending on the temperature. The
latter two are therefore commonly given as qualifiers, as for this
example.
