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.

  1. Water is an Anomaly to the general rules of phases of matter because it has less density in its solid phase than its Liquid phase. This means that ice forms on the ( TOP or BOTTOM) of a freezing body of water.
  2. Absolute Zero is the temperature when a substance has no Kinetic Energy and the atoms are no longer moving.
  3. Both liquids and gases are considered Fluids 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 Incompressible fluid and a gas is considered a compressible 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?

  1. Melt some wax in a beaker.
  2. Allow the wax to cool slowly
  3. Observe the progression of freezing.

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 Illustration

Gas particles are in constant rapid random motion.

Gas particles are so small that they may be considered to

have NO VOLUME relative to the empty space that

surrounds them.

Collisions 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

Temperature of the gas.
