What is Matter? by Elijah Mccoy

Matter - is anything that has mass and takes up space. It can be a pure substance and mixture.

Horses are matter, they are living and they take up space.

There're two types of matter. Pure Substance and a Mixture. First I will focus on the pure substance section.

Pure Substance can be classified as either an element or a compound. I'm going to talk (at this moment) about Elements.

An element is - a part or aspect of something abstract, especially one that is essential or characteristic for example Bromine. Bromine is - a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly colored gas.

Now I am going to talk about the compound side of Pure Substance. A compound is - a thing that is composed of two or more separate elements. For example H2O (aka water) is a compound that consist of 2 hydrogen atoms and 1 oxygen atom.

That's all for the Pure Substance part if things. So now I am going to talk about mixture. Mixture is - a substance made by mixing other substances together. There two kinds of mixtures. Homogeneous and Heterogeneous. First I am going to talk about the Homogeneous kind.

Homogeneous mixtures only have one part to them, solutions. A solution is a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). Rubbing Alcohol is an example of a solution.

Now I am going to talk about the Heterogeneous side of Mixture. There are two kinds of Heterogeneous Mixtures. Suspension and Colloid. I am going to talk about Suspension first. Suspension is - a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction. Example: flour in water

The last thing that want to talk about is Colloids. Colloids are - Heterogeneous, noncrystalline substance consisting of large molecules or ultra microscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension. For example: Paint. Paint is - a colored substance that is spread over a surface and dries to leave a thin decorative or protective coating.
