How is chemical change different from a physical change?
1 answer:
A physical change changes the form of the matter, but does not change the substance itself.
A chemical change affects the substance and turns into a different substance.
Ex:
Physical change: Water freezes- its changes form, but it is still water
Chemical change: Wood burns- it is changing its makeup from wood to ash and various gases. You cant identify it as wood anymore.
