conductivity
n. uncountablen. the ability of a material to let heat or electricity pass through it. Metals usually have high levels of this.
n. the degree to which a specified material conducts electricity or heat. Often expressed as a physical property that varies depending on temperature and material purity.
Copper is used in wires because of its high conductivity.
The technician measured the water's electrical conductivity to check for the presence of dissolved salts and minerals.
In semiconductor manufacturing, controlling the conductivity of silicon through doping is essential for creating the transistors that power modern computing devices.
From conductive + -ity.
Uncountable in its general sense; can be used with 'high', 'low', or 'thermal' to specify the type of energy transfer.
