Mass - the amount of matter in an object. • 1. The mass of an object is constant. Mass does not change as an object is moved from one place to another. For example, when you go to the moon, all your body parts are still attached even though you weigh less! • 2. Measured in grams (g) or kilograms (kg).
Matter can be classified in to two broad categories: pure substances and mixtures.
Pure Substances are Elements - all the same type of atom. Compounds - substances made from two or more different kinds of atoms.
Mixtures are either Homogeneous • Mixtures which are the same throughout with identical properties everywhere in the mixture. • Not easily separated. • This type of mixture is called a solution. A good example would be sugar dissolved in water
or Heterogeneous • Mixtures which have different properties when sampled from different areas. • Examples of this would be sand mixed with water or peanuts mixed with raisins.
