Answer

Brief Explanations:

Intensive properties do not depend on the amount of substance. Superconductivity (resistance dropping to zero at low - temps) is an inherent property of the material and does not depend on the quantity of the superconductor. Electrical power and temperature are not what's being described here. Extensive properties depend on the amount of substance, and superconductivity is not one.

Answer:

The scientist is observing an intensive property of a superconductor.
