Exploring Physical and Chemical Changes

The video tutorial explains the differences between physical and chemical changes using steel wool as an example. Initially, steel wool is introduced, highlighting its metal-like feel and common use for cleaning. The video then demonstrates a physical change by tearing the steel wool into smaller pieces, noting that its chemical composition remains unchanged. In contrast, when steel wool is burned, it undergoes a chemical change, resulting in new substances and a blackened appearance. This illustrates the fundamental differences between physical and chemical changes.
