noun Physics.
the phenomenon of almost perfect conductivity shown by certain substances at temperatures approaching absolute zero. The recent discovery of materials that are superconductive at temperatures hundreds of degrees above absolute zero raises the possibility of revolutionary developments in the production and transmission of electrical energy.

Superconductivity
is always a great word to know.
So is heat. Does it mean:
| nonmechanical energy transfer with reference to a temperature difference between a system and its surroundings |
| a unit of energy, the work done by a force of one newton when its point of application moves through a distance of one meter in the direction of the force |

superconductivity  (s 'pər-kŏn'dŭk-tĭv'ĭ-tē) Pronunciation Key
The ability of certain metals or alloys to conduct an electric current with almost no resistance. Superconductivity usually occurs close to absolute zero, at temperatures approaching -459.67°F (-273.15°C), but has also been observed at temperatures as high as -200°F (-128.88°C). superconductor noun |

superconductivity [(sooh-puhr-kon-duk-tiv-uh-tee)]A property of materials by which their electrical resistance goes to zero, and they acquire the ability to carry electric current with no losses whatsoever.
Note: Formerly, materials showed superconductivity only near absolute zero, but new materials have been found that are superconducting at much higher temperatures.
superconductivity [(sooh-puhr-kon-duk-tiv-uh-tee)]
A property of some materials in which their electrical resistance drops to zero, and they acquire the ability to carry electric current with no loss of energy whatsoever. Formerly, materials developed superconductivity only at temperatures near absolute zero, but new materials have been found that remain superconductive at temperatures above those of liquid nitrogen. The goal of current research is to find a material that remains superconductive at room temperature.
