2. What does Temperature
have to do with changes in the states of matter?
Lets watch the video clip to find out!!

4. There are 4 states of matter although
we focus on the 3 states of matter.
Solid
Liquid
Gas
Solid
                                                 
Liquid
                                             
                                                 

5. Solid p. 33 A substance which has definite shape
and definite volume. The molecules are
slow moving (vibrate in place).
A solid has boundaries and is not
easily compressed.

6. Amorphous Solid p. 33 A type of solid having molecules
which move faster and is structurally
less rigid than a normal solid.

7. Very orderly arrangement
Crystalline Solid
p. 33
Very orderly arrangement
of particles in a solid.

8. Iron, diamond or even ice are considered Crystalline solids because their molecules are in an orderly arrangement p.33

9. Who put the solids in my liquid?
A substance which has no definite shape but has a definite volulme.
The molecules are fast moving molecules which flow. Liquids
have an interface (boundary), and can’t
be easily compressed.
Liquid
p. 34

10. Surface Tension p. 34 The force that acts on the
surface of a liquid and that tends to
minimize the area of the liquid.
Surface Tension p. 34

11. Surface Tension p. 34 The attraction of molecules to each
Try this definition!!
The attraction of molecules to each
other on a liquid's surface. Thus, a
barrier is created between the air
and the liquid.

12. Viscosity
The resistance of a
gas or liquid to flow. P 34

13. Gas p. 35 A substance which has no definite shape or volume, no
boundaries, can be easily compressed, with
extremely fast moving molecules.
