can you describe the physical property of density and give an example of how it can be useful like an 8th grader

Answer 1

Density is a physical property that measures how tightly packed the particles in a substance are. It is calculated by dividing the mass of an object by its volume.

An example of how density can be useful is in determining if an object will sink or float in a liquid. For instance, a piece of wood has a lower density than water, so it will float on the surface. On the other hand, a metal object has a higher density than water, so it will sink. This concept is important in understanding buoyancy and designing objects such as boats and submarines.
