An intensive (physical) property is one that is?

An intensive property is characterized by its independence from the quantity of matter present in a substance. This means that intensive properties remain constant regardless of the size or mass of the sample. Examples of intensive properties include temperature, pressure, density, and color. These properties provide significant information about the material itself, irrespective of how much of the material there is.

In contrast, extensive properties depend on the amount of matter. For instance, mass and volume are extensive properties because they change when the amount of substance changes. An intensive property’s constancy is crucial in many practical applications, such as identifying substances and understanding their behavior under various conditions.
