Properties Vs. Changes

Properties describeChanges actually occur

Physical changeAlters the appearance of a

substance, but does not change the composition.

What was composition again?

Examples of physical changes

All phase changesMelt/freezeVaporize/condenseSublimation/deposition

Chemical Change

AKA, chemical reactions, involve the changing of one or more substances into a new substance.The new substance has new

physical properties.

Law of Conservation of Mass
