The boiling point and color of a substance are both examples of intensive properties because they do not depend on the amount of matter in the sample.
Intensive properties are characteristics of a material that remain the same regardless of the size or quantity of the sample. For example, no matter how much water you have, its boiling point remains at 100 degrees Celsius at standard atmospheric pressure. Similarly, the color of a substance, such as copper, is a property that does not change whether you have a small piece or a large block of it. This distinguishes them from extensive properties, like mass and volume, which do vary based on the amount of material present.
