The Science of Cooking
Every time you cook, you're a chemist! Cooking involves changing matter in all sorts of ways—mixing, heating, freezing, and more.
Everyday Chemistry
- Baking a cake is a chemical change, as new flavors and textures form.
- Boiling water is a physical change—you're just changing liquid water to steam.
- Mixing oil and vinegar for salad dressing is a physical change (no new substances are created).
Understanding chemistry helps you become a better cook and experiment safely with recipes!
Examples
Caramelizing onions creates new flavors through chemical reactions.
Dissolving sugar in lemonade is a physical change.
