Lower density materials would work their way to the top of a free moving solution.
A good way of remembering density is visualizing the "D" for density being a bow an arrow. Then think of the m/v being a heart.

Fingerprints are a good way to identify people because they cannot be confused or faked, and each person has a unique set, even identical twins, so they can't be confused that way either.
maybe ask your teacher would help googleit *The density is the mass of 1 cubic metre of the material. That way you can compare different materials
Hardness alone is not a good way to identify a mineral, other properties such as streak color, cleavage, opacity, ect also need to be taken into consideration. There is no "quick way" to properly identify a mineral.
Density can be used to determine buoyancy. To find out of something will float or sink, density is a good way to make a prediction.
to identify a good milk, need to smell it. if it smells wired than its bad. another way is to tast it. if it tasts sawer that's its bad
The energy density is higher than for other materials, and water has an anomalous density change right around the freezing (melting) point.
