1. Phases of Matter

2. The 3 different phases of matter are solid, liquid and gas.

3. 1. SOLIDS • Solids have two important characteristics: definite mass and volume.

4. The particles in a solid are closely packed together. The movement of particles in a solid is what we would call a vibration.

5. Examples: Ice, sugar, metal, coin . . . Ice hotel!

6. 2. LIQUIDS • Liquids do not have any specific shape, but take the shape of the container in which they are placed. They do have a definite volume.

7. The particles in a liquid are close together but are free to move around each other. • Example: water, honey, motor oil

8. 3. GAS • Gases do not have a definite shape or volume. A gas fills the space available.

9. The particles in a gas are spread very far apart from one another. There is a lot of empty space between each particle

10. When matter is converted from a solid (ice) to a liquid (water), and to a gas (steam), heat energy is required. The density of a substance is decreased with the addition of more energy.

11. Hot Air Balloons

12. Rail Roads and Thermal Expansion
