MATTER #1

1. Intensive Properties - do not depend on the amount of matter that is measured

1.1. Density - the degree of compactness in an object

2. Mixtures - made of of two or more different substances which are mixed buy are not combined chemically

2.1. Colloids - looks like a homogenous mixture, but is not the same throughout

2.2. Homogeneous - mixture is the same throughout

2.3. Heterogeneous - not the same throughout. ex. salad, wood, car...

3. Extensive Properties - property of matter that varies with the amount of matter

3.1. Mass - property that reflects the amount of matter in an object

3.2. Volume - the amount that a substance can hold inside of it

4. Definition of Matter - physical substance in general

5. Chemical change - any change that results in the formation of a new chemical substance

6. Properties of Matter - anything that has mass or takes up space

6.1. Liquid - takes the shape of its container, definite volume

6.2. Solid - definite shape, definite volume

6.3. Plasma - indefinite shape, indefinite volume

6.4. Gas - takes shape of its container, indefinite volume

7. Classification of Matter - based on physical or chemical properties in a substance

7.1. Pure Substances - A pure substance is a sample of matter with both definite and constant composition with distinct chemical properties.

7.2. Suspensions - a heterogenous mixture containing solid particles

7.3. Solutions - a homogenous mixture composed of only one phase

7.4. Element - substance that cannot be broken down chemically or physically

7.5. Compound - two elements equally balanced together

8. Physical Change - where a substance is altered but no new substance is formed from this change
