Quizplus · Accepted Answer

Superconductors are materials that can conduct electricity or transport electrons from one atom to another with no resistance. This phenomenon typically occurs at low temperatures. The critical temperature at which a material becomes superconducting varies depending on the material. Among the options given, 90 K is a recognized critical temperature for certain high-temperature superconductors, notably the yttrium barium copper oxide (YBCO) class of cuprate superconductors. This temperature is significant because it is above the boiling point of liquid nitrogen (77 K), making such superconductors more practical for applications due to the relative ease and economy of cooling to the operational temperature.
