Definition

quality of a liquid material entity that is the resistance of the liquid surface to an increase in surface area, arising from unbalanced cohesive forces between molecules at the liquid surface

Examples

• the surface tension of a protein formulation containing polysorbate; the surface tension of a liquid drug product during fill-finish; the surface tension of a buffer solution used for membrane wetting; the surface tension of a cleaning solution used for equipment cleaning; the surface tension of a cell culture medium containing antifoam or surfactant;

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

SurfaceTension(x) → Quality(x) ∧ ∃m∃s (MaterialEntity(m) ∧ qualityOf(x, m) ∧ LiquidAggregateState(s) ∧ hasQuality(m, s))

Semi-Formal Natural Language Axioms

if x is a ‘surface tension’ then x is a ‘quality’ that is the ‘quality of’ some ‘material entity’ that ‘has quality’ some ‘liquid aggregate state’
