Objective - To distinguish between physical & chemical changes in matter.
A physical change is a type of change in which the form of matter is altered but one substance is not transformed into another. Examples of physical changes are boiling, melting, freezing, and shredding.
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting.
