1. Phases of Matter
Cornell Notes page 125

2. Kinetic Energy
The amount of energy an object possesses due to it’s motion.

3. A type of energy (thermal energy)
Heat

4. Kinetic Molecular Theory
Explanation of how particles in matter behave
Adding energy/heat to a molecule speeds up the motion of the molecules and increases the space between them, (removing heat does the opposite.)

5. Temperature
A measure of heat (energy)

6. Definite
Indefinite
Clearly defined or determined
Fixed (stays the same)
No fixed limit; unlimited
Not clearly determined
Doesn’t stay the same

7. Molecule
One or more atoms chemically combined to make a single molecule.

9. Solids
Definite volume
Definite shape
(solids keep their shape and keep the same volume, no matter what container they are in)
Molecules form a rigid structure
Low energy

10.
Molecules in a solid

11. Liquids
Definite volume
Indefinite shape
(liquids maintain the same volume, but will take the shape of their container.)
Molecules slide past each other
Higher energy level

13. Gases
Indefinite volume
Indefinite shape
Gases expand to fit their container, changing both volume and shape
Molecules move freely past each other
Highest energy level
