Physical Changes: What Is a Physical Change?

The video tutorial explains the difference between physical and chemical changes. Physical changes involve alterations in size, shape, color, or appearance without changing the matter's actual makeup. An example given is tearing paper, where the paper remains the same despite being in smaller pieces. In contrast, chemical changes result in a new type of matter, as demonstrated by burning paper, which turns into ash. The video emphasizes understanding these changes through practical examples.

Can you provide an example of a physical change and explain why it is classified as such?

What occurs to paper when it is burned, and how does this illustrate a chemical change?
