What will happen to the molecules of a substance as you add thermal energy (heat)?

Open the States of Matter: Basics PhET using this link. This link will open the simulation in a new window.

Once the simulation opens, select "States"

Or, you can use use the simulation embedded below.z

Now go back to solid water.
Use the slider under the container to add heat. Gradually add heat to the water until it becomes a liquid then a gas.
Describe what you observe as you add heat.

Now bring the slider down toward "cool" to remove heat. Continue cooling until the water is in the solid form.
Describe what you observe as you remove heat.

Select a new substance from the choices on the right: Neon, Argon or Oxygen.

Click the down arrow next to the thermometer and change the temperature to Celsius.

Start in the solid state and gradually add heat. Based on the motion of the particles, try to determine the temperature where the substance becomes a liquid, and then a gas. In "show your work" submit a screenshot of your substance as a solid, a liquid and a gas. Be sure to label which is which.

The substance I picked:

Becomes a liquid at:

Becomes a gas at:

Now look up the melting point and boiling point of the substance you chose. (You can use Google)

I chose:

The melting point is: .

The boiling point is:.

Before we go, let's review the vocabulary for when a substance changes state.

Melting is when changes to .

Evaporation is when changes to .

Sublimation is when changes to .

Condensation is when changes to .

Freezing is when changes to .

Deposition is when changes to .
