VIDEO-MOLECULES OF LIQUIDS
All solids consist of _______________ of matter which are continuously
vibrating to and fro in ___________________________. It is this
___________________________.of _______________ that keeps the solid from
falling apart. The scientific word for _______________ is _______________ .

1. As the heat of sun acts on molecules what happens to them?
2. What happens when the force of attraction can no longer hold the molecules together?
3. What happens to an object when the lattice work pattern no longer exists?
4. What word describes the phase change causing this breakdown of order?
5. What happens when a liquid gets cold?

VIDEO- EVAPORATION AND CONDENSATION
As the ________________ in a solid get hotter, they vibrate faster and faster,
until their mutual force of attraction is no longer strong enough to hold them
together. This causes them to slip out of their ______________________,
which therefore falls apart. When the __________________________ of
________________ in a solid has collapsed; we say that the solid has melted-It
has changed from a ________________into a ________________.
1. Are liquid molecules arranged in a lattice work pattern?
2. How would you explain the arrangement of liquid molecules?
3. What happens to some of the molecules that rise to the surface of the liquid?
4. What phase do these molecules that are “released into the air” form?
5. What is the process called when some molecules are “released into the air”?
6. What is the process called when vapor turns back into liquid?
7. Explain the process of condensation. (How does it happen?)

VIDEO-EXPANSION AND CONTRACTION
1) When _______________ “escape” from a _______________ , they
spread out in all directions to form a _______________ or _______________ .
This process is called _______________ the change of state from a
_______________ to a _______________ .
When _______________ _______________ are cooled, they go slower
and crowd together more _______________ to form a _______________ .
This process is called _______________ the change of state from a
_______________ to a _______________.
2. What happens if you blow a balloon partially full and leave it in the sun?
3. Using the answer from question number one, why does this happen to the balloon?
