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 molecular theory is
based upon the assumption that atoms are in constant ____________ ______________.
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
Lowest Kinetic Energy
In between Kinetic Energy
Highest Kinetic Energy
Lowest Density
High Strength Bonds
Highest Density
Weak Bonds
No Bonds
3. ____________ _____________ is directly related to temperature. As the temperature increases so does
the ____________ _____________ .
4. Compared to Solids and Liquids gases tend to have a lower ___________. This can be explained by the fact
that there is so much __________ ______________ between particles in a gas.
5. A small pressure will easily ___________ a gas. If this happens its ____________ will increase. The space
between the atom will (INCREASE or DECREASE).
6. Even a large pressure will not __________ a solid because the atoms are so closely packed.
7. Solids have strong _________s, liquids have weaker________s and gases have no_______s holding them
together.
8. A solid like ice or diamond has a highly ordered arrangement of bonds between atoms which is called
its____________. A liquid or gas does not have this.
8. Water is an __________ to the general rules of phases of matter because it has less ___________ in its
solid phase than its ___________ phase. This means that ice forms on the ( TOP or BOTTOM) of a freezing
body of water.
9. ___________ ________ is the temperature when a substance has no Kinetic Energy and the atoms are no
longer moving.
10. Both liquids and gases are considered ___________ because they flow easily. However the density of a
liquid can not be changed easily while the density of a gas can be changed by compressing it. Because of this
a liquid is considered an _____________ fluid and a gas is considered a ______________ fluid.
DESCRIBE AN EXPERIMENT – We know that the solid form of water (ICE) is less dense than the liquid form of
water ( LIQUID WATER). When water freezes it starts at the top and freezes down through to the bottom. A
scientist thinks that wax will also freeze from top to bottom. Describe the steps of how a scientist would test
this?
THE KINETIC THEORY - Fill in the blanks and draw the picture to illustrate the rule.
According to the notes the Kinetic Theory describes gases as follows:
Rules of Kinetic Theory
Gas particles are in constant rapid ______ _______.
Illustration
Gas particles are so small that they may be considered to
have NO VOLUME relative to the ________ _______ that
surrounds them.
_________ are perfectly elastic. Velocity is unaffected by the
collisions or motion of the other particles.
The average velocity of the particles is directly related to the
_______________ of the gas.
High Temp
Low Temp
