Do Superconductors Heat Up?

Do Superconductors Heat Up? Do superconductors heat up? superconducting wire What happens when you heat a superconductor? All superconducting materials stop being superconductors when they are warmed up. Each superconductor has a “critical temperature”, below which it superconducts, and above which it is just an ordinary material which resists electrical flow. Are all superconductors cold?
