Answer:

You call it a low temperature phenomenon because you need to cool a conductor to a very low temperature for superconductivity to occur.

Explanation:

A metallic conductor has an electrical resistance that decreases the lower the temperature is. When the conductor is cooled to a temperature below its critical temperature, the electrical resistance drops to zero and that phenomenon is called superconductivity.
