Superconductivity= material has zero resistivity/resistance, resistivity decreases with temperature
Conditions needed: becomes superconducting when you reach the critical/certain/transition temperature
Critical Temperature= temperature at or below which a material becomes a superconductor/has zero resistance/resistivity
