Cutting a piece of wood is a physical change because the chemical composition of the wood remains the same before and after cutting. The change is only in the physical appearance and shape of the wood.
Decaying of wood is a chemical change since it leads to the formation of a different substance. The process is irreversible.
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.

Physical change.
Yes, chopping a piece of wood with an axe is a physical change. The physical appearance of the wood changes as it is cut into smaller pieces, but the chemical composition of the wood remains the same.
Wood rotting is a chemical process that occurs as a result of fungi breaking down the components of wood through enzymatic reactions. This process leads to the decomposition of wood fibers and the release of chemical byproducts.
In my living environment, a chemical change occurs when food is digested in the stomach, where complex molecules are broken down into simpler ones. In my non-living environment, a chemical change occurs when iron rusts due to exposure to oxygen and moisture, forming iron oxide.
When a piece of wood burns, it undergoes a chemical change. This process involves the wood reacting with oxygen in the air, resulting in the production of heat, light, and ash. Unlike physical changes, which do not alter the substance's chemical composition, combustion transforms the wood into different substances, indicating a permanent change.
It is a physical change from a rough to a smooth surface.
