Before you open the simulation:
PREDICT
1. Draw a diagram below showing what you think the molecules
will look like for each state of matter, solid, liquid, and gas. Write a
sentence below each diagram predicting what the motion of the molecules will be
like.

|
Sentence explaining how molecules will be moving.
|
They will remain
close together and hardly move.
|
They will be separate and will take the shape of the container.
|
They will bounce around throughout the container.
|
2. If you start with a substance as a solid, what will
happen to the molecules as you add thermal energy (heat)? It will turn into a
liquid and eventually turn into a gas- as the temperature rises.
ONCE YOU HAVE
COMPLETED THIS PAGE, YOU MAY BEGIN THE SIMULATION.
Open the simulation. You will find it in a folder on your desktop labeled “States of Matter Simulation.”
Open the simulation. You will find it in a folder on your desktop labeled “States of Matter Simulation.”
INVESTIGATE:
3. Use the menu on the right side of the program to select
Water and Solid. Draw and describe what you see in the space below.
|
Diagram
|
Description
|
 |
The molecules are bouncing around and are sticking
together. They seem to be vibrating or
shaking.
|
4. Now, use the slider on the bottom of the program to Add
Heat. Notice the thermometer at the top of the program. What temperature scale
is this thermometer showing? Kelvin
5. What happens to the water as you increase the
temperature? The molecules
spread out and begin to separate and sporadically move. Turning into a liquid and gas.
6. What is the melting/freezing point of water in
Kelvin? 373.33 K, 273.15 K
7. Add heat until the temperature is just below and then
just above the melting point of water. How is water different below its melting
point and above it? They both act about
the same.
8. Draw and describe what water looks like as a liquid.
|
Diagram
|
Description
|
 |
They are bouncing around quickly in a group- like
structure.
|
9. What is the boiling/condensation point of water in
Kelvin? 373.15 K
10. Continue to add heat until you are just below and then
just above the boiling point of water. How is water different below its boiling
point and above it? They seem to
appear to be about the same.
11. Draw and describe what water looks like as a gas.
|
Diagram
|
Description
|
 |
The molecules are bouncing around, and not clumped
together at all.
|
12. Choose one of the other three substances listed in the
menu on the right. Investigate what happens when you add and remove heat from
this substance. Use the buttons on the right to see this substance as a solid,
liquid, and gas. Draw and describe its properties in the table below.
Substance Selected: Neon

|
Sentence explaining how molecules are moving.
|
The molecules are in a square shape and bouncing together.
|
The bouncing is faster but they are still somewhat in a
clump.
|
They have separated and are bouncing around more quickly.
|
ANALYZE:
13. How was this substance similar to water in each state of
matter? How was it different? As a solid, Neon was more tightly
compacted than water was. As a liquid, Neon did not shake as much and wasn’t as
spread out as water. As a gas, Neon was
moving much more slowly than water was shaking and more spaced out as well.
14. Were your predictions (see p. 1) correct or incorrect?
Explain. My predictions were
correct because I knew that solids wouldn’t be moving as much as liquids and
gases.
BONUS: Optional,
worth up to 10 points added to the lab’s final grade
15. Choose a substance other than water from the menu on the
right side of the program. Use the slider to add and remove heat. Based on what
the molecules do, figure out the approximate temperatures of the melting point
and boiling point of this substance. (Hint: The temperatures given when you
click solid, liquid, and gas are NOT the melting and boiling points.)
Substance: Argon
Melting Point: 92
K
How did you figure it out? It looked like it started to change into a liquid by separating and
moving around and quicker.
Boiling Point: 199
K
How did you figure it out? The molecules are completely spread out and moving around
everywhere.
3. The Hydrogen atoms all connect to one another.
4. Temperature: 493 K Pressure: 19-20 ATM
5.
C.4.6 Communicate the results of their investigations in ways their audiences will understand by using charts, graphs, drawings, written descriptions, and various other means, to display their answers
We used charts and drawings to display what was happening with the solids, liquids, and gases.
D.4.5 Construct simple models of what is happening to materials and substances undergoing change, using simple instruments or tools to aid observations and collect data
The website we used had simulations so that we could easily see what was happening with the different states of matter.
