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
One chemical property of wood is its combustion, which releases heat energy through a chemical reaction with oxygen. One physical property of wood is its density, which can vary depending on the type of wood species and its growth conditions.
Chemical: flammability requires a chemical reaction to occur in the presence of oxygen at a sufficiently high temperature.
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.
Burning wood is a chemical process because it involves a chemical reaction between the wood and oxygen in the air to produce heat, light, and new chemical compounds such as carbon dioxide and water vapor.
Chopping wood for a fire is a physical change because the wood's size and shape are altered. Burning the wood is a chemical change because it undergoes a chemical reaction to produce heat, light, and other byproducts.
Chopping wood is a physical process, not a chemical reaction, so it does not produce heat or absorb heat. However, when wood burns, that is an exothermic reaction because heat is released as a result of the combustion process.
Fashioning a table leg from a piece of wood involves physical changes. The process of cutting and shaping the wood is a physical change as the composition of the wood itself remains the same, just the form and size are altered.
