A. Name the three states of matter

2. STATES OF
MATTER

3. Topic: Solids, Liquids and Gases
EQ: How are the attractive forces between particles different in solids, liquids and gases?

4. The Three States of Matter
Solid
Liquid
Gas

5. Two factors affect the state of matter
1. The amount of energy of particles present (this can change).
2. The distance between particles
Background information:
Atoms have (-) and (t) parts that attract each other

6. Kinetic Theory of Matter
Matter is made up of particles which are in continual random motion.

7. STATES OF MATTER SOLIDS
Particles of solids are tightly packed, vibrating about a fixed position.
Force between particles:
Slow movement + particles being close together =strong attractive forces.
These forces hold them together so they cant slide past each other = definite shape and volume

8. STATES OF MATTER LIQUID
Particles of liquids are tightly packed, but are far enough apart to slide over one another.
Force between particles:
Move faster than solid and the particles are further apart.
Because particles move faster= weaker attractive forces. Particles can slip past each other= indefinite shape and volume

9. STATES OF MATTER GAS
Particles of gases are very far apart and move freely.
Force between particles:
Particles are very far apart = low attractive forces so the particles can slide past each other very easily. This makes them have an indefinite shape and an indefinite volume.

10. Description of Phase Change
PHASE CHANGES
Description of Phase Change
Term for Phase Change
Heat Movement During
Phase Change
Solid to liquid
Melting
Heat goes into the solid as it melts.
Liquid to solid
Freezing
Heat leaves the liquid as it freezes.

11. Summarizing Activity A. Cut out figure 1 on page. 264
Label each diagram by indicating which figure is a solid, liquid or gas.
B. Explain how the attractive forces and the distance between the particles impact the state of matter of each. How does this impact the state of matter.

Phase Change
Liquid to gas
Vaporization, which includes boiling and evaporation
Heat goes into the liquid as it vaporizes.
Gas to liquid
Condensation
Heat leaves the gas as it condenses.
Solid to gas
Sublimation
Heat goes into the solid as it sublimates.

13. STATES OF MATTER LIQUID SOLID GAS Tightly packed, in a regular pattern
Vibrate, but do not move from place to place
Close together with no regular arrangement.
Vibrate, move about, and slide past each other
Well separated with no regular arrangement.
Vibrate and move freely at high speeds
