Conductivity

Business / Construction / Conductivity: The rate at which heat is transmitted through a material.

Electrical Conductivity

Science / Chemistry / Electrical Conductivity: A measure of how easily an electric current can pass through a material. The conductivity is the reciprocal of the resistance. The SI unit of conductance is the siemens. MORE

Superconductivity

Science / Chemistry / Superconductivity: The ability of certain materials to carry an electric current with zero electrical resistance. MORE

Hydraulic Conductivity

Science / Geology / Hydraulic Conductivity: A measure of the permeability of a rock or soil: the volume of flow through a unit surface in unit time with unit hydraulic pressure difference as the driving force. MORE

Thermal Conductivity

Science / Geology / Thermal Conductivity: A measure of a rock's capacity for heat conduction. MORE
