A scientist observes that the electrical resistance of a superconducting material drops to zero when the material is cooled to v
k0ka [10]

Answer:

The scientist is observing an intensive property of a superconductor.

Explanation:

An intensive property is a bulk property of matter. This means that an intensive property does not depend on the amount of substance present in the material under study. Typical examples of intensive properties include; conductivity, resistivity, density, hardness, etc.

An extensive property is a property that depends on the amount of substance present in a sample. Extensive properties depend on the quantity of matter present in the sample under study. Examples of extensive properties include, mass and volume.

Resistance of a superconducting material has nothing to do with the amount of the material present hence it is an intensive property of the superconductor.

Olegator [25]
So, personally, I think it's not that safe to live right by a nuclear plant because it contains radioactive energy and that is unhealthy to the human body. Living by one a person should also take the precautions that it could have a malfunction and that could cause a fatal accident, an explosion. With that radioactive energy is released and both ruins the area and destroys everything. Well my answer is not that great but I hope this helps.
