Physical and Chemical Changes - Chemistry | Socratic
Acting upon matter can cause it to change, but it is useful to separate these changes into two different egories: physical and chemical. A chemical change describes a process that changes one material into another. Burning wood causes it to turn into ash, a different material. A physical change is simply changing the shape or state, such as cutting a piece of wood into two pieces.
