TEAS 7 CHEMISTRY- PHYSICAL PROPERTIES,
STATES OF MATTER, AND WATER Qs & As
1. Kinetic
Theory that all matter is composed of particles (atoms and molecules)
Molecular
moving constantly in random directions.
Theory
Molecule motion changes as is heat added or removed.
2. What does the 1. Temperature
phase of a sub- 2. Pressure
stance depend
on?
3. Mass Amount of matter in an object, the number of molecules
4. Volume Amount of space occupied by a specific number of molecules
5. 3 states of matter 1. Solid
2. Liquid
3. Gas
6. Solid 1. Fixed shape and volume
2. High pressure
3. Low temperature
4. High atomic attraction
7. Liquid 1. Fixed volume but changing shape (takes shape of container)
2. High pressure
3. Higher temperature
4. Weaker physical bonding
8. Gas 1. Changing volume and shape
2. Low pressure
3. Higher temperature
4. Weaker atomic attraction

, TEAS 7 CHEMISTRY- PHYSICAL PROPERTIES,
STATES OF MATTER, AND WATER Qs & As
Change from one state (solid or liquid or gas) to another without a
change in chemical composition.
Involves adding or removing heat.
10. Exothermic A reaction that releases energy in the form of heat
reac- tion
11. Endothermic A reaction that absorbs energy in the form of heat
reac- tion
12. 2 external
1. Temperature
factors that
2. Pressure
affect matter
state
13. Vaporization Liquid --> Gas
Spontaneous phase
change
Adding heat = endothermic reaction
14. Evaporation Liquid -->
Gas Phase
transition
Adding heat
Happens at boiling point and depends on atmospheric pressure
15. Condensation Gas --> Liquid
Phase change
Removing heat = exothermic reaction
16. Freezing Liquid -->
solid Phase
