2. Solids Liquids and Gases
How strong are the attractive forces in solids, liquids, and gases?
How are the participles arranged in solids, liquids and gases?
What is the movement in solids, liquids and gases?
The particles in a solid are very close together, they move slowly. The shape of
a solid is always a specific shape. They have very close attraction.
The particles in a liquid are not to close but not to far apart, they move pretty
fast but not as fast as a gas. The shape of the liquid is the shape of the beaker.
The attraction is medium attraction.
The particles of a gas are very far apart, they move very fast. The gas does not
have a shape. They have no attraction at all.

What are the three phases of matter?
Solids, Liquids and Gases
Solid
Liquid
Gas

4. Solids Liquids and Gases
What has to happen in order to get a phase
change?
You have to add energy.
You take away energy to get it back to a solid.

5. Solids Liquids and Gases
What has to happen in order to give us
pressure?
The gas particals hit the side of an object.For
example a box with gas inside would blow the
cap of the box.

6. Solids Liquids and Gases
What happens when we heat Solids Liquids and
Gases?
When we heat up a solid it turns into a liquid. After a
while it starts to boil and the gas comes out. Heat
makes the particles move faster.
For example:

Why do solids, liquids, and gases expand when we heat them
up?
They expand because when you heat a solid, liquid or gas the
heat tears the molecules apart, which means they can move
more.

8. Solids, Liquids and Gases
What is melting, boiling, freezing, vaporization, condensation,
and sublimation?
Melting=The temperature at which a solid turn into a liquid.
Boiling=The temperature at which the liquid boils.
Freezing= The temperature at which a substance changes from a liquid into a
solid.
Vaporization= The change of a substance from a liquid to a gas.
Condensation=A gas turns into a liquid.
Sublimation=A solid turning directly into a gas.
