What is Matter? By: Kejamion ross

What is matter? Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. Matter is made up of two substances Pure Substance and Mixtures, but first i am going to explain Pure Substances.

Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together). Pure substances are made up of elements and compounds. A compound is a pure substance composed of two or more different atoms chemically bonded to one another. Lastly an element is a part or aspect of something abstract, especially one that is essential or characteristic.

Now i'm going to explain what a mixture is, and what its made of. A Mixture is a substance made by mixing other substances together. For example a mixture is like salt water because of the mixture of water and various salts.

Homogeneous Mixture: A mixture which has uniform composition and properties throughout. For example, air is a homogeneous mixture of gases. A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture.

Heterogeneous Mixtures. A mixture is a combination of two or more pure substances in which the original substances retain their chemical properties.

A substance that dissolves into a solvent, forming a solution. SOLUTION. A special mixture formed when a material dissolves into water. An example would be like ice in water it would dissolve.
