Is there an equation for the molecular changes in water ?

Question

When water goes from liquid to vapour and ice, is there an equation for the changes in molecular motion involved ? Does this equation (assuming there is one) describe a regular curve on a graph ?

Answer 1

Are you referring to the changes in energy?

I only ask this because the molecular structure does not change no matter in what physical form the water is.  It is H-O-H regardless; two hydrogen atoms covalently bonded to a single oxygen atom.

Edit:  Ok, I thought you were talking about the kinetic energy model, which is a modified bell curve.  Check this site out.  (I didn't read the whole thing, so I don't know if it's completely what you're looking for.)  http://mse-092697c.princeton.edu/rahman/...
