Physical and Chemical Changes

Physical Change Physical change: a change that occurs that does not change the identity of the substance Melting ice(change in state or phase) Freezing Kool-aid Tearing paper Boiling water

Chemical Changes Chemical change: a change that occurs causing the identity of the substance to change Burning Digesting food Reacting with other substances A chemical change is called a chemical reaction

Chemical Changes Cont’d Indicators of a chemical change: Gives off light Gives off heat Produces a gas Color change Formation of a precipitate

Is it Physical or Chemical? Change Physical Chemical Melting cheese Burning wood Milk souring Wadding up paper Bicycle rusting
