Molecular Workbench Model
Solids
1. RUN the model by clicking the PLAY button of the player. How do the molecules move?
2. While the model is running, click and watch the added molecule.
3. Now, while the model is still running, click and watch the second molecule.
4. Reset the model by clicking the BACK button of the player. Check the box under the model frame, and then run the model
and follow steps 2,3 once again while it is running.

Intermolecular forces in the solid state of matter
false
<font size=3><b>Intermolecular forces</b>, represented here by dotted lines between molecules, <br>are the strongest in the solid state of the matter.<br>These forces have effect only if the molecules are close enough.<br>The strong intermolecular forces keep the molecules fixed in their positions <br>and prevent molecules from moving away from their neighbors.<br>It takes energy to overcome the strength of the intermolecular forces, <br>and when enough energy is added, a phase change occurs.
