Chemical/Physical Change PowerPointTara Polk9/18/092nd Period

DefinitionsPhysical Change- A change in matter which does not alter the chemical properties of the matter. Chemical Change- A rearrangement of the atomic array of matter which results in a change of physical properties.

Chemical ChangeAn example of a chemical change would be cleaning a penny, because the vinegar and salt cause a chemical reaction in the penny, which strips the dirt and rust off of the penny.

Physical ChangeAn example would be, if you carve a piece of wood into a baseball bat. It would be a physical change because the wood is only changing size & shape, a new substance is not created.
