Storyboard-Text
- My teacher said that we have to give examples of physical and chemical changes! Hmm, I'll ask my sister for help.
- Oh? What happened to you? I was just about to ask you for some help.
- I accidently cut my papers for my activity!
- I just want to ask if you have any idea with physical and chemical changes?
- In any case, what do you want to ask?
- Since only the physical characteristics, such as size and shape, are altered when paper is cut, but the chemical composition stays the same, that is a physical change.
- Really? Can you enlighten me more?
- Oh? The one that I did right now is an example of physical change!
- Really?
- As ash, a brand-new substance, is created during the process and oxides of carbon are also produced, it involves chemical change.
- On the other hand, as soon as I set these papers on fire, it's now an example of chemical change.
- Always remember, Physical changes involve a change in the substance's shape or appearance but not its composition. In contrast, a chemical change alters the nature of the matter and results in the formation of at least one new substance with new features.
