The Strange Chemical And Physical
Chemicals and Physical changes are going to become Awesome!
A chemical change is when a object turns into a new substance basically, change object to different object. If you watch the video "Amazing chemical reactions" you will see many chemical reactions, but when you see the first chemical reaction, soda fizzes but they use a different thing not mentos.
The Extreme Diet Coke & Mentos Experiments
Amazing chemical reactions!
A physical change is when it changes but is still the same thing. For example, an ice cube melts, it changes its type of matter but is still the same thing. If you watch "Extreme soda challenge" the soda fizzing is a physical change because it is still soda.
You may not think rusting is a chemical change but it is because rust can change the car's texture.
This egg changed it texture just like the rust so this is also a chemical change.
BURN BABY BURN!
When a match gets lit it changes by the fire and making a new substance.
