Hello, My name is Yazmin and today I'm going to tell you all about Chemical and Physical change. Your probably wondering what im talking about!
well a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur, and no new compounds are produced.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds but cannot usually be used to separate compounds into chemical elements or simpler compounds.
many people ask the same question "What is the difference between a physical change and a chemical change?"
