conductivity

This term describes a passive physical property rather than an active process. It functions as a scale of efficiency, where high conductivity suggests a path of least resistance and low conductivity suggests a barrier or insulator. It is a technical term used primarily in physics, engineering, and chemistry to quantify how easily energy moves through a medium.

In a broader sense, the word conveys a feeling of openness or permeability. While a conductor is the object itself, conductivity is the inherent quality that determines how effectively that object performs its role in a circuit or heat exchange system.
