If the wood was burned, that would be chemical change
An example of a chemical reaction is burning a piece of wood. During this process, wood reacts with oxygen in the air to produce carbon dioxide, water vapor, and ash, resulting in a chemical change. In contrast, melting water, dissolving salt in water, and breaking a tree branch are physical changes, not chemical reactions, as they do not alter the chemical composition of the substances involved.
Chemical change is a process in which reactants are changed to form one or more than one products. During a chemical change there is rearrangement of atoms i.e, breaking and formation of new bonds.This change is not reversible. For Example: # burning of wood # change in temperature or energy,as in exothermic or endothermic reactions. # formation of precipitate in a reaction.
The rotting of back steps is a chemical change. This is because the deterioration of the wood is caused by a chemical reaction with oxygen and water, breaking down the molecular structure of the wood over time.
No, wood being carved is a physical change because the chemical composition of the wood is not altered. The act of carving simply changes the shape and form of the wood without changing its chemical structure.
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.
physical change
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not 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.
Combustion (burning) is a chemical change.

Wood rotting is a chemical change. It involves the decomposition of the wood's organic compounds through biological processes like fungi and bacteria breaking down the cellulose and lignin in the wood.
Burning wood in the fireplace is an example of a chemical change because the wood undergoes a chemical reaction to produce heat, light, and ash. This change is irreversible as the wood is transformed into new substances during the process.
Chemical change is a process in which reactants are changed to form one or more than one products. During a chemical change there is rearrangement of atoms i.e, breaking and formation of new bonds.This change is not reversible. For Example: # burning of wood # change in temperature or energy,as in exothermic or endothermic reactions. # formation of precipitate in a reaction.
That change would be physical, since the chemical identity of the wood has not been altered by cutting it.
Burning wood. When the wood is burned, it becomes black.
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.
Wood. When wood burns, it undergoes a chemical change that breaks it down into ash and gas, releasing energy in the process. This decomposition by fire is a chemical change, transforming the wood into different substances.
