How does the behavior of atoms and molecules differ between solids liquids and gasses?

Answer 1

Since this is not my area of expertise, I searched Google under the key words "solid liquid gas molecules" to get these possible sources:

http://www.edinformatics.com/math_science/states_of_matter.htm

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
