NTR: quality of a colloidal suspension, of an aerosol

[pbuttigieg]

Similar to quality of a liquid etc.

quality of a colloidal suspension
preliminary def:
A physical quality inhering in an entity by virtue of the bearer's solid constituents being suspended in a liquid or gas, or the bearer's liquid constituents being suspended in a gas.

with a subclass

quality of an aerosol
preliminary def:
A physical quality inhering in an entity by virtue of the bearer's solid or liquid constituents being suspended in a gas.

Continuing this theme, quality of a suspension was requested over at EnvironmentOntology/envo#484

This has consequences for the label of:

quality of a colloidal suspension

There's some semantic fuzziness here, but generally suspensions are not like colloids in that they will eventually settle.

Thus, we propose:

• the label of quality of a colloidal suspension be changed to quality of a colloid and the def updated to:
  • A physical quality inhering in an entity by virtue of a portion of the bearer's molecular or polymolecular constituents present in one phase being dispersed in a portion of the bearer's constituents present in another phase. (xref IUPAC Gold Book)
• a class for quality of a suspension be created with the def:
  • A physical quality inhering in an entity by virtue of the bearer's solid or liquid constituents being transiently dispersed in a solid, liquid, or gas before settling due to gravity or centrifugal forces.

For suspension, note that IUPAC definitions speak only of solid dispersed in liquid, however many alternate usages seem to exist.
