Unit b matter and chemical change notes (matter & states of matter)

1. Unit B
Matter and Chemical Change

2. What is matter?
• Matter: The stuff that makes up the universe that is
not energy
• Matter:
1. Has mass
2. Takes up space

3. The Particle Model of Matter
1. All matter is made of tiny particles
2. Particles are in constant motion
3. There are attractive & repulsive forces between particles
4. These are spaces between the particles
5. Difficult matter is made of different particles

5. States of Matter
States of Matter: distinct forms in which matter can
exist.

9. Changes Between States of Matter
Melting: Going from a solid to a liquid when heat is added
Boiling: Going from a liquid to a gas when heat is added
Condensation: Going from a gas to a liquid when heat is
removed
Freezing: Going from a liquid to a solid when heat is removed
Sublimation: Going from a solid to a gas when heat is added
Deposition: Going from a gas to a solid when heat is removed
