When identifying extensive properties, remember that they depend on the quantity of the substance present, such as mass, volume, or total heat capacity.
Extensive properties are those that depend on the amount or size of the substance present in the system. They are proportional to the quantity of material.
- Density is an intensive property because it does not depend on the amount of substance. It is a ratio of mass to volume.
- Volume is an extensive property because it is directly proportional to the amount of substance present. The more substance you have, the greater the volume.
- Heat capacity is also an extensive property because it depends on the quantity of material. A larger amount of material will absorb more heat for a given temperature change.
Thus, Volume is the correct answer as an extensive property.
