Final answer:
Intensive properties that correctly answer the question are the density, temperature, and boiling point of a substance. These properties do not depend on the amount of the substance present and are characteristics inherent to the substance.
Step-by-step explanation:
The question asks to identify which of the given options are intensive properties. Intensive properties are those that do not depend on the amount of the substance present, and they are inherent to the substance itself.
- Density of a substance
- Temperature of a substance
- Boiling point of a substance
The boiling point and temperature do not change with the amount of substance and therefore they are intensive properties. Density is an intrinsic characteristic that remains constant regardless of the sample size.
