What type of property is independent of the amount of material present?

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

Answer: (A)

Intensive properties are defined by their independence from how much material you have. They describe the state of the system per unit amount, so whether you measure a small sample or a large one, their values stay the same. Temperature, pressure, and density for a homogeneous substance are classic examples.

Extensive properties, on the other hand, scale with the amount of material: mass, volume, total energy, and total entropy change as you add more material. A derived form like specific volume or specific energy is obtained by dividing an extensive property by mass, making it intensive, but the core idea the question targets is the fundamental independence from quantity.
