Molecular Workbench Model
Liquids
1. RUN the model by clicking the PLAY button of the player.
2. While the model runs, check the box below.
Are the molecules always stay attracted to the same neighbors?
You can mark one molecule for help with this question.
Note: The temperature of the liquid in this model is constant, since you don't add heat (nor do you you cool the liquid down). Recall that temperature is a measure of the average kinetic energy of the molecules; That is why the average kinetic energy also stays constant in this model.

Inter- and Intra- molecular forces
12041
false
<font size=3><b>Intermolecular force</b> is a force that exists <font color=green> between </font>two molecules. For example, <br>between one H<sub>2</sub>O molecule and another H<sub>2</sub>O molecule, or between two blue balls in the model. <br>Another type of force exists <font color=green>within</font> the molecule, for example between the O atom <br>and the two H atoms within the water molecule. The second type of force is called <b>Intramolecular force</b>.<br>The representation of a molecule as a ball hides its atoms and does not show intramolecular forces at all.
