A scientist observes that the electrical resistance of a superconducting material drops to zero when the material is cooled to very low temperatures. Which of the following statements best describes what the scientist is observing?
A. The scientist is observing the electrical power of a superconductor.
B. The scientist is observing the temperature of a superconductor.
C. The scientist is observing an intensive property of a superconductor.
D. The scientist is observing an extensive property of a superconductor.

Respuesta :

Answer:

It should be C,

Explanation:

It's intensive, that is mass independent.

resistance occurs due to electron movement,

for R=0, no electron movement should be there, hence intensive property.
