A material is said to be a superconductor if when it is brought down to a critical low temperature it loses its resistivity completely.
A superconductor is a material that has zero electrical resistance at certain temperatures. For example, in a ring of superconducting material, if you induce a current to flow in a circle, it will continue flowing for ever. So far, it has only been possible to create superconductors at cryogenic (i.e., "supercold") temperatures.
Superconductivity is a property of a substance at a given temperature, not of a substance at any temperature.
Superconductors are things that have no electrical resistance when they are at low enough temperatures, typically close to absolute zero i.e. 0 Kelvin or about -273 degrees C.
There are also 'high-temperature' superconductors that operate at about 70 degrees K (-203 degrees C).
We haven't yet found a substance that works as a superconductor at room temperature there is a lot of research on-going. The aim is to try to find metal alloys or other substances that will behave as superconductors at temperatures which are much closer to room temperature than to absolute zero i.e. 0 Kelvin or about -273 degrees C.

Water is not a superconductor.
No. Salt water is a conductor but not a superconductor.
Technetium is a superconductor under 7,46 K.
No, Mercury the planet is not a superconductor. Even mercury the metal is not a superconductor, under normal temperatures.
Low temperature. A superconductor doesn't 'perform' at all, and isn't even a superconductor, above its critical temperature.
Yes, a superconductor has zero resistance.
A superconductor superconducts ONLY at extremely low temperature.
A superconductor. It has zero resistance, and therefore zero resistivity.A superconductor. It has zero resistance, and therefore zero resistivity.A superconductor. It has zero resistance, and therefore zero resistivity.A superconductor. It has zero resistance, and therefore zero resistivity.
An ideal superconductor has exactly zero losses, thus resistance is zero.

it can be a superconductor
Any electrons flowing through a superconductor will show up as a regular electric current.
An example of a superconductor is mercury. Superconductivity is an element's ability to have no electrical resistance when cooled to temperatures close to absolute zero.

A current of electricity can flow at the same strength for an indefinitely long time in a superconductor but only for as long as the superconductor is held below its critical temperature. If its temperature were allowed to rise to its critical temperature - or higher - the material would no longer behave as a superconductor: it would acquire resistivity which would restrict the flow of current.
That's a "superconductor".
