Physical+Change

Physical Change is when the looks of the atom change, but the atom is still what ever it was before the change. ie. ice to water, water to water vapor, and so on. It is a cyclic causality because the temperature, which comes to play in a lot of physical change experiments, can just be changed of you can just filter out the solids from the liquids, like a cycle.

Some labs that we did that were examples of physical change were the change of state lab and the separating mixtures lab. The reason the separating mixtures lab was a physical change was because even though the salt dissolved in the water, the didn't mix to form a new compound. The change of state lab was obviously a physical change, because the ice turned into water, then water vapor. Although all of these things are different states of mater, they are all water.
