“measure of mass per unitVolume”

Relative “heaviness” of anobject

Density = mass/volume

Density examplesOil and vinegar salad dressing: The oil floats on the vinegar water mixture, while the solids sink to the bottom.

Oil spills: What happens when an oil tanker leaks on the ocean? The oil floats on the water since it is less dense, and this provides some opportunity to clean up the oil spills by skimming the oil from the surface of the water.

Ice: Everyone knows that ice floats on water, but did you know that this is an abnormal physical property of solid/liquid state of water? The more normal physical property is for the solid of a compound to sink in its own liquid.
