2  Matter- Anything that has mass and takes up space  Substance – A single kind of matter that is pure, has a specific set of properties  Examples: Table Salt, Table Sugar, Baking Soda  Not Examples: Flour, Milk, Eggs, Fruit

3  Physical Properties -characteristics of a pure substance that can be observed without changing it into another substance.  Examples: Physical State, Texture, Color, Shape, Hardness, Flexibility, dissolves in water,luster, etc.

4

5  A characteristic of a pure substance that describes its ability to change into a different substance  Examples:  Flammability (Combustion)  Ability to React (Oxidation/Tarnishing)

6

7  Freezing water  A rusting nail  Burning a log  Digesting food  A chameleon changing color  Melting cheese

8  An element is a pure substance that cannot be broken down into any other substances. The basic particle of an element is an atom. Elements are the simplest substances  Examples: Aluminum, Oxygen, Carbon, Gold, Silver, Sodium, Nitrogen, Neon  When atoms combine they form a chemical bond (the force of attraction between two atoms).  Molecules are groups of two or more atoms held together by chemical bonds.

9  When atoms combine they form a chemical bond (the force of attraction between two atoms).  Molecules are groups of two or more atoms held together by chemical bonds.  Examples: Water (H 2 O), Oxygen (O 2 ) Carbon Dioxide (CO 2 ) Carbon Monoxide (CO)

10  A compound is a pure substance made of two or more elements chemically combined in a set ratio. Ex: C0 2 or H 2 0  A mixture is made of two or more substances (elements, compounds, or both) that are together in the same place but are not chemically combined. Each substance in a mixture keeps its individual properties  Example: soil, tossed salad, sand

11  Homogeneous Mixture: A mixture that is so evenly mixed that you can’t see the different parts  Examples: Salt Water, Sugar Water, Brass  Heterogeneous Mixture: A mixture in which you can see the different parts  Examples: Damp Soil, Salad, Omlet

12  Use a magnet  Filter the mixture  Use distillation  Evaporation

13  Mass- the amount of matter in an object  Units are the kg or g  Volume- the amount of space matter occupies. (formula: V= l x w x h)  Units are L, mL, and cm 3  Density- the mass of a material in a given volume. (formula: mass/volume)  Units are g/mL or g/cm 3

14

15  Solids - definite shape and definite volume  Liquids - definite volume but no definite shape  Gas - no definite volume and shape  Plasma - a gas-like state consisting of a mixture of free electrons and atoms that are stripped of their electrons

16

17  Melting - change in state from a solid to a liquid.  Melting point - particles of a solid substance are vibrating so fast that they break free from their fixed positions  Freezing - change in state from a liquid to a solid.  Freezing point - particles of a liquid are moving so slowly that they begin to form regular patterns.

18  Vaporization - particles in a liquid gain enough energy to form a gas  Evaporation - vaporization that takes place at the surface of a liquid.  Boiling - a liquid changes to a gas below and at the surface of a liquid  Condensation - particles in a gas lose enough thermal energy to form a liquid  Sublimation - particles of a solid do not pass through the liquid state as they form a gas
