Matter and its Properties Read through the notes and fill out your concept map to classify matter
What is Matter? Matter can be defined as anything that has mass and takes up space. All matter has mass and volume. Volume is the amount of 3-D space an object occupies. Mass is a measure of the amount of matter in an object.
Classification of Matter There are 2 ways you can classify matter. Pure Substances Mixtures
Pure Substances Consist of elements and compounds. An element is a pure substance made of only 1 kind of atom. An atom is the smallest unit of an element that keeps the properties of that element.
EXAMPLES Carbon, Hydrogen, and Oxygen are all examples of individual elements. Each element specifically contains only 1 kind of atom. **This makes each element a pure substance.
The Compound… A compound is a substance that is made of 2 different elements that are chemically bonded. Compounds consist of molecules. Ex} Water is an example of a compound. It is made of 2 elements, hydrogen and oxygen. The atoms of Hydrogen and Oxygen are chemically bonded to form a water molecule.
Mixtures… A mixture is a blend of 2 or more kinds of matter, each of which retains its own identity and properties. The can be classified as: homogeneous heterogeneous
Homogeneous Have a uniform composition Meaning they have the same proportion of components throughout or they are mixed evenly. Homogeneous mixtures are also known as solutions. Kool-Aid Soda
Heterogeneous Are not uniform throughout.. Meaning the particles are unevenly distributed. Clay& Water Seeds
Heterogeneous Mixtures Suspension heterogeneous large particles particles settle EX: fresh-squeezed lemonade, Baby medicine
Heterogeneous Mixtures Colloid heterogeneous Strong Tyndall effect particles don’t settle EX: Whip Cream, Butter, Fog, milk
Tyndall Effect
Separating Mixtures Can be separated by physical means such Sorting Filtering Boiling/Distillation Evaporation Melting Chromatography Paper Chromatography Sorting erasers Filtering- Oil
Separating Mixtures Distillation Set-up
On the Back of your Concept Map: Define the following terms: Colloid (and list the examples) Suspension (and list the examples) Tyndall Effect Copy: “Mixtures can be separated by physical means such as:” and then list the ways… Show me for a STAMP grade when you are done
