Chemical Change

Mr. Anderson explains the differences between chemical and physical changes, using examples like rotting fruit and rusting iron. He discusses how chemical changes involve forming new substances, while physical changes involve changes in state. Evidence of chemical changes includes changes in odor, color, gas production, heat, and precipitate formation. The video also covers laboratory examples of chemical changes, such as acid-base reactions and redox titrations.
