Atomic Forces and State
The forces between atoms are key to understanding the states of matter and evaploration
How does the strength of the force between atoms effect their state?
Use the following model to explore this question. Things to know about the model:
You can use the slider to change how strong the forces are between atoms.
The temperature of this model stays constant at 300K, about room temperature.
The state of matter at a particular temperature depends on how strong the forces are between particles. Substances with strong forces between atoms tend to be solids at room temperature and will have high melting and boiling points. Substances with weak forces 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 forces.
Next page, we will look at how the forces between atoms determines the strengths of materials.
