Question

Give an example where density is used to identify the substance composing an object. Is additional information needed for objects composed of more than one material?

a) Density is not used for identification.
b) Archimedes' principle; additional information is needed.
c) Density is used for all materials.
d) Additional information is not needed.

Answer 1

Density can be used to identify the substance composing an object, but additional information is needed for objects composed of more than one material.

Step-by-step explanation:

Density is a physical characteristic of matter that can be used to identify the substance composing an object. For example, if you have two objects with different densities, you can determine which substance each object is made of by comparing their densities.

However, when an object is composed of more than one material, additional information is needed to identify the substances. This could include knowing the densities of the individual materials or conducting further tests to determine their composition.
