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

Answer: (C)

Verified step by step guidance

1. Understand the difference between intensive and extensive properties: Intensive properties do not depend on the amount of substance present, while extensive properties do depend on the amount.
2. Identify the properties listed: Volume, Length, Density, and Mass.
3. Recall that Volume, Length, and Mass change when the size or amount of the sample changes, so these are extensive properties.
4. Recognize that Density is defined as mass divided by volume, \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\), and it remains the same regardless of the sample size.
5. Conclude that Density is an intensive property because it does not depend on the amount of gold in the bar.
