Types of Matter
Matter can be classified under 2 types, matter that is a pure substance and matter that is a mixture of more than one pure substance. From this basic difference we can classify matter even further.
There are two types of pure substances:
There are two types of pure substances:
When elements and compounds are mixed together (not bonded together), a mixture is made. Mixtures can be classified in three categories:
The other two types of mixture can both be put under the category of heterogeneous mixtures. In these kind of mixtures, two or more pure substances are together, but with visibly different parts. In heterogeneous mixtures, you will be able to see at least two different parts. The category of heterogeneous mixtures can be further divided into two parts:
Suspension
Mixture in which particles of one substance settle to the bottom. Examples: Italian Dressing, Water and Oil |
Colloid
Mixture in which the different parts can be seen, but the particles do not separate and settle out. Some colloids particles are sometimes small enough they cannot be seen to the unaided eye. These particles can be detected however by scattering light due to the Tyndall effect. Examples: Fog, Concrete, Gravel, Sand |
