Why some metals have 0 resistance at 0 kelvin

[nipiano93]

Hey someone please explain why some metals have 0 resistance at 0 kelvin (absolute zero).
Please explain the complete mechanism properly.

Er... what you are describing is NOT superconductivity. Superconductivity doesn't have to occur only at 0 K. That's the whole point of this phenomenon. High Tc superconductors have a transition temperature often above 100 K!

Based on your question, I'm not sure if you're asking about the phenomenon of superconductivity, or if you want to know why metals are projected to have zero resistance at 0K. The latter isn't a superconductor because zero resistance isn't the only criteria for superconductivity (Meissner effect, etc.)

So please provide further clarification.
