Which of the following is an example of an intensive property?

An intensive property is a characteristic of a substance that does not depend on the amount of material present. Essentially, it remains constant regardless of the sample size. Density is a prime example of an intensive property because it is defined as mass per unit volume (mass/volume), and this ratio remains unchanged whether you have a small sample of a material or a larger one.

In contrast, mass, volume, and length are extensive properties, as they do depend on the amount of substance present. For instance, if you have a larger sample of a material, both the mass and the volume will increase. Therefore, while density provides crucial information about a substance that is independent of its quantity, mass, volume, and length will vary based on how much of the substance is present.
