Well a physical change is when you break something and you still have it like ripping a piece of paper. You still have the paper!! Then you have your chemical change .Which is when you do something to make it to the point were you cant keep it.(EX) Burning a piece of paper in the fire is a chemical change:) Because you cant get it back:)
A chemical reaction is when two or more substances mix together and change to form new substances. It's like mixing ingredients to bake a cake – you can't go back to the original ingredients once the cake is baked.
Producing soot by burning something is a chemical change, but when it is deposited on metal (or anything else), that is a not a chemical change.See the Related Questions to the left for more information.
Something burning is a chemical change because it is combining with the oxygen in the air. Ex. when you burn sugar you get c02 and water, the reason the water doesnt put out the fire is that the water is released as a gas.
it can't be changed,i.e.,irreversible change...
