Which property is not considered an extensive property?

• A. Mass
• B. Volume
• C. Densitiy
• D. Length

Answer: (C)

Densitiy is considered an intensive property rather than an extensive one because it does not change with the amount of substance present. Extensive properties, like mass, volume, and length, do depend on the quantity of the material. For instance, if you take half of a sample, the mass and volume will also be halved, reflecting the proportionality to the amount of material. In contrast, density, which is defined as mass per unit volume, remains constant regardless of the size of the sample. This intrinsic characteristic of density illustrates its classification as an intensive property, distinguishing it clearly from the other choices listed, which are all extensive.
