Which is not an intensive property?

• A. Mass
• B. Volume
• C. Colour
• D. Density

Answer: (A)

Mass is not an intensive property because it depends on how much material you have. Intensity means the property stays the same no matter how much substance you take. If you double the amount of material, you double its mass, so mass scales with amount. The same is true for volume—it also increases with more material, so it’s not an intensive property either. In contrast, color stays the same regardless of how much material you have, and density is a fixed ratio of mass to volume for a substance, so it doesn’t depend on the amount. That’s why mass is a clear example of a non-intensive (extensive) property, and why the other options behave differently.
