In present day technology, a substance can become a superconductor
A) at temperatures above 0 Kelvin but less than 100 Kelvin.
B) only at absolute zero temperature.
C) at room temperature.
D) at a temperature above the boiling point of water.

Question

Quizplus · Accepted Answer

Superconductors can operate at temperatures above 0 Kelvin but less than 100 Kelvin. Current technology has not yet achieved room temperature superconductivity, and superconductivity above the boiling point of water is also not feasible with known materials. Absolute zero is not a requirement for superconductivity; many materials become superconducting at higher temperatures.
