Presentation Transcript

1. Physical and Chemical Changes Unit II�Part 2

2. Concept of Change Change: the act of altering a substance

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

4. Chemical Changes Chemical change: a change that occurs causing the identity of the substance to change Burning Digesting food Reacting with other substances (give an example per reviewer) A chemical change is called a chemical reaction

5. Chemical Changes Cont�d Indicators of a chemical change: Evolution of light Evolution of heat Evolution of a gas Color change Formation of a precipitate

6. Is it Physical or Chemical?
