as temperature increases solubility (amount that can dissolve)
particles vibrate in place are very close together and have the lowest kinetic energy
particles move more freely, are a little further apart and have an average amount of kinetic energy
particles are moving very fast in all directions and are very spread out and have a high level of kinetic energy
solid changes to a liquid. energy must be absorbed
gas changes to a liquid. energy must be released therefor particles slow down.
