States of Matter
Learning Goal:
Students will be able to demonstrate their knowledge of the states of matter through illustrations and
descriptions. These illustrations and descriptions should include:
• How the molecules in a solid, liquid and gas compare to each other.
• How temperature relates to the kinetic energy of molecules.
Purpose:
Hypothesis:
Predict what the molecules of a solid, liquid and gas look like. Illustrate your prediction with a drawing.
Solid
Liquid
Gas
Procedure:
• Click on the “Virtual Lab” link
• Click on “State of Matter Tab” and use simulation to test states changes for each of the four
substances.
• Record your results in the table.
• Open the “States of Matter” Simulation and select “Run Now”
Investigation:
1. Complete the table below by exploring the “Solid, Liquid, Gas” tab in the simulation. Test your
predictions and record your observations by recording the temperature and illustrations of each
substance in the three states of matter.

2. Write a summary, detailing the changes that affect each of the substances as its pressure is increased
or decreased. Be sure to give your finding for each of the four substances.
3. Write a summary paragraph, detailing how the distance affects the forces of attractions between the
atoms. Be sure to give your finding for each of the two substances.
4. Write a summary paragraph, to demonstrate you have mastered the learning goal. Be sure to
incorporate both concepts of the learning goal:
•
How the molecules in a solid, liquid and gas compare to each other.
•
How temperature relates to the kinetic energy of molecules.
Journal Questions:
5. Explain how a change in temperature affects the pressure inside a container.
6. Explain this phase diagram by relating what you know about temperature, states of matter and
pressure.
Lab Questions:
1. After observing heat being added to the substance, was your prediction correct or incorrect?
Explain.
2. What do you think will happen to the substance, the atomic or molecular activity, and the
shape of the graph when thermal energy is removed from the substance?
3. After observing heat being removed from the substance, was your prediction correct or
incorrect? Explain.
4. What do you think the effect of pressure has on each of the atoms? Do you think the effect of
temperature is greater than pressure? Explain why or why not.
5. What is your opinion on the effect of distance between atoms?
