if you chop down a tree and cut it into a bunch of little peices... can you put that tree back together so that it can continue on living its boring tree life? the answer is no it is irreversible
It's irreversible, since the wood turns to charcoal/ash and gases. You cant then make wood out of the final products after combustion.
non- reversible
Irreversible
Neither. It is not a physical change.
It is irreversible.
Reversible change😊

Cutting down a tree. shredding of paper
cutting yourself. the scar would always be there....
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
Burning wood is a chemical change.
Reversible.
Cutting down a tree. shredding of paper
It is an irreversible change because the saw dust cannot be rejoined to make the wood again.
No
It disintegrates to ashes.

burning or tree or wood is an irreversible chemical change.
It depends on how you bend the wood. For example, if you steam it, it is reversible. But if you cut notches, it is not reversible.
They are the result of two or more reactants usually combining. You can identify when a chemical reaction has occured by a change of state being physical e.g. liquid to gas. The product may change in colour, taste, smell, temperature, size etc. You can also tell if it starts to effervest - bubble. There are reversible and irreversible chemical reactions. Reversible is obviously when you can change the effects e.g. you can melt and re-solidify water whereas irreversible you can't e.g. can't turn ash back into wood when burnt. Hope that helps (;
Do the logs change from wood to some other substance? No, so it has to be a physical change.
Decaying of wood is a chemical change since it leads to the formation of a different substance. The process is irreversible.
no once the wood has burned you cant unburn it
