Learn
about solids, liquids and gas. What is the relationship of
atoms to each.
Solids
Knows that atoms in solids are close together and don't move
around easily;in liquids, atoms tend to move further apart;
in gas atoms are quite far apart and move around freely.
Solids
are materials in which the atoms or molecules are set in place.
In most solids each unit may have its own spot in which it
fits(as in sugar crystals). The common point about solids
is that the atoms or molecules are set in place. Solids have
no independent linear motion of translation because they are
attached to on another.
Kids
Picture a class of sixth graders glued to their seats. Each
kid can jump up and down and sideways and turn their chair
around, but they can't move out of place. Another example
is a junkyard of springs. The springs have all been tied together
in one enormous ball. Each spring can twist and vibrate, but
it can't yet loose from its neighbor.
Liquids
Liquids are materials in which the atoms or molecules are
close to each other as solids, but the materials can slip
over each other to change places.
B-B's
You might view liquids as B-B's in a dump truck. Consider
a big dump truck going fast down a bumpy road. The B-B's have
some energy from the bumpy road. A few B-B's are always in
the process of getting enough energy to hop out of the dump
truck. Like Bb's, liquids have no shape except that of the
container. In liquid the forces that hold the particles together
are greater than the forces that try to pull the partials
away from each other.
Gases
Gas, or vapor, is the most energetic phase of matter commonly
found here on earth. The partials of gas, either atoms or
molecules, hare to much energy to settle down attached to
each other.
