what is matter by richard walters

matter is a physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
Matter has pure substance and a mixture.

I'm going to explain what a pure substance is in this section. Pure substances are defined as substances that are made of only one type of atom or only one type of molecule. There are 2 kinds of pure substances, an element and a compound.

A compound is a pure substance composed of two or more different atoms chemically bonded to one another. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two. A couple of several examples of compounds are water , salt , methane and sugar .

An element is a pure substance which cannot be broken down by further chemical techniques. Several examples of elements are Hydrogen,Carbon, and Oxygen.

In this section I am going to explain mixtures.

A mixture is a substance made by mixing other substances together. There is two kinds of mixtures called homogeneous and heterogeneous

A Homogeneous mixture contains two or more gaseous,liquid,or solid substances blended evenly throughout the mixture

A solution is a homogeneous mixture of two or more substances. Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water.

The other mixture is called a heterogeneous mixture and that is a mixture in which different materials can be easily distinguished.

suspension is a heterogeneous mixture containg a liquid in which visible particles settle.

examples of an suspensions are water and dish washing soap and salt water.

The definition of a colloid is a combination of molecules mixed through other substances that will not settle out or join with the other substance.

Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, and paper.

i hope you have learned a little about what I explained to you.
