2. What is Density?
Density is the property that indicates how much mass is concentrated in an object.
It is the relationship between the mass of an object and its volume.
For example, a cubic centimetre of water has a mass of one gram. Its density is therefore one gram per cubic centimetre (1g/cm3).
Matter is more concentrated in some substances than in others. For example, matter is more concentrated in metal than in wood or plastic. A metal ball has more mass than a plastic ball with the same volume. Therefore, its density is higher.
