All of the following are examples of EXTENSIVE properties of matter EXCEPT volume, number of atoms, length, and the state of matter.
The Correct Answer and Explanation is:
Correct Answer: The state of matter
Explanation:
In chemistry and physics, properties of matter are categorized into two main types: extensive properties and intensive properties.
- Extensive properties depend on the amount of matter present in a sample.
- Intensive properties do not depend on the amount of matter and remain the same regardless of sample size.
Let us analyze each option:
- Volume – This is an extensive property because the volume increases as more matter is added. For example, 2 liters of water has twice the volume of 1 liter.
- Number of atoms – This is also an extensive property because the number of atoms is directly related to the quantity of the substance. If you double the amount of substance, you double the number of atoms.
- Length – Length is an extensive property. For example, if you have a piece of string and you cut it in half, each half has a different length. The total length depends on how much material there is.
- State of matter – This is not an extensive property. The state of matter (solid, liquid, or gas) is an intensive property. It depends on temperature and pressure, not the quantity of the material. For instance, a glass of water and a bucket of water can both be in the liquid state even though they have very different amounts of matter.
Therefore, the state of matter is not an extensive property. It does not change with the size or amount of the sample. It is more related to the physical conditions the matter is under.
In conclusion, among the options given, the only non-extensive property is state of matter, making it the correct exception in this question.
