Final answer:
The density of pure mercury remains at 13.6 g/cm³ regardless of the sample size, because density is an intensive property that does not vary with the amount of substance. so, option 1 is the correct answer.
Step-by-step explanation:
The density of a substance is a characteristic physical property that is independent of the amount of substance present. This means that regardless of the size of a sample of a pure substance, its density remains the same. The density of a droplet of pure mercury is given to be 13.6 g/cm³. Therefore, when considering a piece of pure mercury that is 10 times larger than the droplet, its density remains 13.6 g/cm³. Option 1 is the correct answer, as mercury's density does not change with size, demonstrating that density is an intensive property.
The density of a substance is defined as mass per unit volume. The density of a droplet of pure mercury is given as 13.6 g/cm³. To find the density of a sample of pure mercury that is 10 times as large as the droplet, we can use the fact that density remains constant. Since the size of the sample is 10 times larger, the volume of the sample will also be 10 times larger. Therefore, the density of the larger sample will still be 13.6 g/cm³.
