Final answer:
Brass has a high density, which is evidenced by the fact that it sinks when placed in water, unlike wood which floats due to its lower density. The density of brass is a crucial property that helps identify its composition and provides information about its phase and substructure.
Step-by-step explanation:
Yes, brass does have a high density. Density is a measure of how much mass is contained in a given volume. If we take an example where brass has the same mass as a block of wood, when both are placed in water, the wood floats while the brass sinks. This is because brass has a greater density than water. Comparatively, wood has a lower density than water, which enables it to float.
The concept of density also allows us to understand the composition of materials. For instance, gold has a density of 19.3 g/cm³, which is significantly higher than many other metals. The density of brass is higher than that of water, which is why it sinks, indicating that it is denser. Moreover, different metals have different densities that can help us identify them. Density not only gives us insight into what the object is made of but also informs us about the phase of matter and its atomic structure.
