If a property changes with the amount of material, it is classified as which type?

• A. Intensive Property
• B. Extensive Property
• C. State Property
• D. Phase Property

Answer: (B)

In thermodynamics, properties are classified by how they scale with the amount of material. An extensive property depends on the size of the system, so doubling the amount of material doubles the property value. Mass, volume, and total energy are classic examples. If a property changes when you change the amount of material, it’s an extensive property. Intensive properties, on the other hand, do not change with the amount of material—they remain the same when you scale the system (examples include temperature, pressure, and density). The term “state property” is about describing the condition of the system and can be either extensive or intensive, so it isn’t the precise label for how the property scales with quantity in this context. The idea of a “phase property” isn’t a standard classification for this purpose.
