- Applies5.8Modeling Using Variation
The end-of-chapter exercise asks why density = mass/volume is intensive when mass and volume are each extensive — the answer is that both are directly proportional to the amount of matter, so their ratio behaves like the constant k in y = kx and is scale-invariant; a student unfamiliar with what direct proportionality formally guarantees can state the fact but not explain it.
