what is a superconductor or why do conducturs conduct electricty better in lower tempratures?

Superconductors are materials with zero electric resistance.
Superconductivity is explained by BCS theory of superconductivity, and beyond the scope of this helpdesk.
It's not the "loose" electrons better called free electrons but coupling between them which reduces the number of collisions and hence the resistance.
