All of the following are examples of intensive properties of matter EXCEPT a. the temperature of matter b. density c. length d. solubility boiling point.
The Correct Answer and Explanation is:
Correct Answer: c. length
Explanation:
Intensive properties are characteristics of matter that do not depend on the amount of substance present. These properties remain the same whether you have a small sample or a large one. Examples of intensive properties include temperature, density, solubility, and boiling point. These features help to identify and characterize substances because they are inherent to the material itself.
Let’s briefly consider each of the options:
- Temperature of matter is an intensive property because it does not change based on the size of the sample. For example, a glass of water and a lake can both have the same temperature, even though their volumes are very different.
- Density is another classic example of an intensive property. It is defined as mass divided by volume. Even if you cut a piece of material in half, each piece retains the same density as the original whole.
- Solubility describes how much of a substance can dissolve in a solvent at a given temperature. It is also independent of the quantity of the material, making it an intensive property.
- Boiling point is the temperature at which a substance changes from liquid to gas. This is a unique and fixed property for each pure substance under constant pressure, so it too is intensive.
On the other hand:
- Length is an extensive property. This means it does depend on the amount or size of the substance. If you cut a rod in half, each piece has a different length than the original. Therefore, it changes based on the sample’s size.
In conclusion, length stands out as the only extensive property among the options. It depends on the amount of matter present, which sets it apart from the others that are true intensive properties.
