Understanding Chemical Reactions: Physical vs. Chemical Changes

The video tutorial explores the differences between physical and chemical changes in matter. It begins with an introduction to chemical reactions and the importance of understanding basic chemistry. The tutorial explains that matter is anything with mass and volume, and chemistry studies matter's properties and interactions. Physical changes, such as changes in state or texture, do not alter the substance's identity, while chemical changes result in new substances. Examples of both types of changes are provided, including crumbling a cookie and rust formation. The video concludes with a review and quiz questions to reinforce learning.

Describe a real-life example of a chemical change and the new substance that is formed.
