States
of matter Model |
|
The different states of matter can be demonstrated by the development of several models. One model that is most effective in demonstrating the properties of each state is outlined below. | |
Material: Drill |
|
Place the slider and the wooden base on top of each other. Drill 20 holes through the slider and into the thick wooden base as shown on the right. Attach the metal rods so that they are firmly held in position. |
|
Place the polystyrene balls at the ends of the metal rods as shown on the right. |
|
When the slider
is pushed to the top, the balls are held together firmly and move about
as a unit. This simulates the particles of a solid. But when the slider
is pushed right to the bottom the balls move about independently at high
speeds when the metal rods are shaken. This simulates the particles of
a gas. Shaking the metal rods indicates energy input in the form of heat.
Moving the slider somewhere in the middle causes the balls to move about
while remaining close to each other, simulating the particles of a solid. |
|
As the slider moves from top to bottom it represents an in temperature. In the gas state, the more energy given to the particles the greater their From our model, we can conclude that particles in a have more energy than the particles of a which in turn have more energy than the particles in a .
