Definition
relational quality that is the magnitude of a particular quality per unit size of the bearer
Examples
- the number density of cells in a culture fluid; the number density of particles in cleanroom air; the mass density of a buffer solution; the radiant energy density in the interior of an irradiation chamber
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs for creating a set of necessary and sufficient conditions
Formal Axioms
First-Order Logic Axioms
Density(x) → RelationalQuality(x)
Semi-Formal Natural Language Axioms
if x is a ‘density’ then x is a ‘relational quality’
