Answer :
Final answer:
A. The bar has a density of 19.2g/mL is an example of an intensive property because density is constant regardless of sample size.
Explanation:
The question asks which option is an example of an intensive property of a bar of gold. An intensive property is one that does not depend on the amount of material present. In contrast, extensive properties depend on the amount of matter. Given the options, A. The bar has a density of 19.2g/mL is an intensive property because density is a characteristic that remains constant irrespective of the sample size. Meanwhile, options B and C (mass and volume, respectively) are extensive properties because they change when the sample size changes. Option D, which refers to the number of atoms, is also extensive, as increasing the amount of gold would increase the number of atoms.
