1. Nature of Matter

2. Intro to Matter
Matter- Anything that has mass and takes up space.
Matter can be a solid, liquid, or gas.

3. Terms to Remember
Volume- The amount of space taken up by an object. The formula for volume is length x width x height or LxWxH.
Mass- The amount of matter in an object.
Weight- A measure of the gravitational force on an object.
Density- The amount of matter in a given space.

4. Physical Properties
Physical Property- A characteristic of a substance that can be measured without changing the substance’s identity.
Some examples of this are color, weight, smell, texture, and volume.

5. More Examples
Thermal Conductivity- The rate at which a substance transfers heat.
State of Matter- The physical form of a substance (solid, liquid, or gas).
Solubility- The ability of a substance to dissolve in another substance.
Ductility- The ability of a substance to be pulled into a wire.
Malleability- The ability of a substance to be rolled or pounded into thin sheets.
Density- The mass per unit volume of a substance (how much matter is there in a certain space). The formula for density is m/V or an object’s mass divided by its volume.

6. Chemical Properties
Chemical Property- The ability of a substance to change into new matter that has different properties.

7. Examples Flammability- The ability of a substance to burn.
Reactivity- The ability of two or more substances to combine to form one or more new substances.

8. Physical Changes
Physical Change- A change that affects one or more physical properties of a substance. Its appearance may change, but the substance hasn’t.
Examples
Smashing a Can
Ripping Paper
Sharpening a Pencil
Ice Cream Melting

9. Hot Gas in a Space Shuttle
Chemical Changes
Chemical Change- When one substance is changed into a new substance with different properties through a chemical reaction. A new substance is formed.
Examples
Hot Gas in a Space Shuttle
Rust
Baking a Cake
Sour Milk
