Intermolecular Forces and State
Use the combo box on the right to explore the relationship between strength of intermolecular forces (IMF) and state. After making your choice, click on run to see what state results.
* Note that the temperature stays constant at 300K (about room temperature) for all these models.

<pre><b><big> Summary</big></b>:<big> The state of matter at a particular temperature
is largely a function of how strong the intermolecular
forces (IMF) are between particles. Substances with
strong IMFs tend to be solids at room temperature and
will have high melting and boiling points. Substances
with weak IMFs tend to be gases at room temperature
and will have low melting and boiling points. Substances
that are liquids at room temperature have intermediate
strength IMFs.
So, what do temperature changes have to do with changes
in state? Click on <b>next</b> below to find out.</big></pre>
