Which of the following is an intensive property?

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

Answer: (A)

Verified step by step guidance

1. Step 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 of substance.
2. Step 2: Analyze each option: Mass, Energy, Volume, and Density. Mass, Energy, and Volume change when the amount of substance changes, so they are extensive properties.
3. Step 3: Density is defined as mass divided by volume, \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\). Since both mass and volume change proportionally, their ratio (density) remains constant regardless of the amount of substance.
4. Step 4: Conclude that density is an intensive property because it does not depend on the size or amount of the sample.
5. Step 5: Therefore, among the given options, density is the intensive property.
