a chemical reaction
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Rottening of wood is a chemical (breakdown) reaction
The burning of a wooden stick is a chemical process.
Chemical: flammability requires a chemical reaction to occur in the presence of oxygen at a sufficiently high temperature.
The cutting of wood is physical.

it is a chemical reaction because a new substance is formed when the wood rots
It is a physical change because it is evaporation. Physical changes can be undone. If it was a chemical reaction it would be permanent like burning wood.
Gold plating on non-metals is a physical change. There is no chemical change when a wood, glass, ceramic, marble or plastic is being plated . However, Electroplating is a chemical change because when a metal is being plated with another metal, there is a chemical reaction.

yes, it is a chemical reaction
maybe. Rotting of wood is a slow chemical process. Trying to cut up a tree with a small knife is slow, but that would be a physical change.
Chemical physical is something like... a dent in metal, a cut in a tree, etc chemical is a reaction like ^acid on chalk or wood burning
Physical. Physical changes include things such as changing shape or color. Chemical changes change the chemical properties of a material, often during a chemical reaction.
