Decaying of wood is a chemical change since it leads to the formation of a different substance. The process is irreversible.
When you burn wood a chemical change occurs.
When you burn wood a chemical change occurs.

Physical. If you were to cut that piece of wood in half what would it be? Still wood. There would be no chemical change. Just a physical change.

The rotting of wood is a chemical change because of many reasons. One of the reasons is because when wood rots, it produces mold, which is a new substance. The definition of chemical change is a change that produces one or more new substances. When the wood rots, you are unable to take the rotted wood and mold and make it back into wood that is yet to be rotted. So because the wood produces one (or more) new substances, the rotting of wood is a chemical change.
Disintegration can be a chemical change, but it depends on what kind it is. For example, sharpening a knife is a physical change, but burning a piece of wood is a chemical change.
when wood rots it is a physical change and not a chemical change.
A physical change because the chemical composition of the wood does not change.
