Final answer:
Electrical conductivity is an intensive property because it remains consistent regardless of the amount of material present, displaying the characteristic conduction behavior of the material itself.
Step-by-step explanation:
The question deals with the concept of extensive and intensive properties in the context of electrical conductivity. Electrical conductivity is considered to be an intensive property because it does not depend on the amount of matter present. It relates to how easily electrons can flow through a material and is characteristic of the material itself, regardless of its quantity. For example, the electrical conductivity of copper is the same whether you have a thin wire or a thick slab of copper.
In contrast, properties like mass and volume are extensive properties because their values change with the amount of substance. However, when you divide one extensive property by another, such as mass by volume to calculate density, the resulting ratio is independent of the amount, thus becoming an intensive property.
