Question

which sequence lists types of materials in order from least conductive to most conductive? superconductor → conductor → semiconductor → insulator insulator → conductor → semiconductor → superconductor conductor → superconductor → semiconductor → insulator insulator → semiconductor → conductor → superconductor

Explanation:

Insulators have very low conductivity as they impede the flow of electric current. Semiconductors have conductivity between insulators and conductors. Conductors allow the flow of electric current easily. Superconductors have zero electrical resistance and extremely high conductivity under certain conditions. So the order from least to most conductive is insulator, semiconductor, conductor, superconductor.

Answer:

insulator → semiconductor → conductor → superconductor
