Chemical Changes

The video explains how baking is similar to chemistry, focusing on the concept of mixtures and chemical changes. It describes how mixtures can sometimes be separated, while chemical changes result in new substances that cannot be undone. Examples include burning a match and baking a cake, both of which demonstrate irreversible chemical changes through color change, heat, and gas release. The video concludes by summarizing the evidence of chemical changes.

How does the process of baking a cake demonstrate a chemical change?

Discuss the significance of heat in the chemical changes that occur during baking.
