The boxes above represent matter in the 3 common phases. Write the name of the phase next to the appropriate letter.
1. The word kinetic comes from a Greek word that means “to move.” The kinetic
m

theory
is
based upon the assumption that atoms are in constant Random Motion
2. State the names of the phases in order of Temperature, Kinetic Energy, density and bond strength
between atoms
Lowest Temperatures
In between Temperatures
Highest Temperatures
Solid
Liquid
Gas
Lowest Kinetic Energy
In between Kinetic Energy
Highest Kinetic Energy
Solid
Liquid
Gas
Lowest Density
Highest Density
Gas
High Strength Bonds
Weak Bonds
No Bonds

Gas
3. Kinetic Energy is directly related to temperature. As the temperature increases so does the Kinetic Energy.
4. Compared to Solids and Liquids gases tend to have a lower density. This can be explained by the fact that
there is so much Empty Space between particles in a gas.
5. A small pressure will easily compress a gas. If this happens its density will increase. The space between the
atoms will (INCREASE or DECREASE).
6. Even a large pressure will not compress a solid because the atoms are so closely packed.
7. Solids have strong Bonds, liquids have weaker Bonds and gases have no Bonds holding them together.
8. A solid like ice or diamond has a highly ordered arrangement of bonds between atoms which is called its
Structure. A liquid or gas does not have this.
