Q.viii. What are intensive properties? Explain why density is intensive property.

Step 1. An intensive property is one whose value does NOT depend on how much of the substance is present -- it stays the same for a small or large sample.

Step 2. Density = mass / volume. Both mass and volume are EXTENSIVE properties -- doubling the amount of substance doubles both mass and volume.

Step 3. Because mass and volume scale together, proportionally, with the amount of substance, their RATIO (density) stays constant regardless of sample size. …

Define intensive properties, then show density is a ratio of two extensive properties (mass, volume) that …

• Calling density extensive because it is 'calculated from' mass and volume, without checking how the RATIO itself behaves with sample size. …
