Final answer:
Density is an intensive property because it does not change regardless of the amount of substance. In contrast, volume, length, and mass are extensive properties that do depend on the quantity. Therefore, density is the best choice from the options given.
Explanation:
Understanding Intensive Properties
In Chemistry, it is important to recognize the distinction between intensive and extensive properties of substances. Intensive properties do not depend on the amount of substance present, while extensive properties do. Among the options provided - density, volume, length, and mass - the density of a substance is considered an intensive property.
For example, the density of water is about 1 g/cm³ at room temperature, regardless of whether you have a glass of water or a swimming pool full of it. On the other hand, volume and mass depend on how much of the substance is present; for example, if you have a larger quantity of water, both volume and mass will increase, but not its density.
Conclusion
Thus, the correct answer to the question is density, as it remains constant regardless of the amount of substance.
