1. MATTER – PART 2

2. WHAT IS MATTER?
Matter -
anything that has mass
and takes up space

3. Mass -
the quantity of matter
contained in an object

4. Weight -
measures force due to
gravity

5. How do we classify
different types of
matter?

6. By Phase or State of Matter
Phase
Particle Properties
Proximity Energy Volume Shape
Solid
Liquid
Gas
close little fixed fixed
close moderate fixed not fixed
far apart a lot not fixed not fixed

8. What is the difference
between chemical and
physical - changes and
properties?

9. Physical Property -
a characteristic of a
material which is
observed without a new
substance produced

10. Examples -
odor, color, volume, state
(solid, liquid or gas)
melting or boiling point

11. Physical Change -
a change where no new
substance is formed

12. Examples -
dissolving, tearing,
hammering, phase
changes or changes of
state:
(solid ↔ liquid ↔ gas)

13. Chemistry - the study
of matter and its
changes

14. Chemical Property -
a characteristic of a
material which indicates
its ability to form a new
substance or not

15. Examples -
flammability, corrosion of
metals, reacting with
oxygen

16. Chemical Change -
a change that results in
the production of a new
substance, also called a
reaction

17. Examples -
Burning, corrosion, baking
a cake
CaO + CO2 → CaCO3
Reactants → Products

18. Four General Signs of a Chemical
Change
1. Gas formed
2. Large energy change
3. Precipitate formed
4. Color change
(change of odor & taste)
