Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.
Heating a wood splinter will lead to combustion, resulting in the release of smoke, ash, and gases due to the breakdown of the organic material. On the other hand, heating glass tubing will not combust; instead, it undergoes physical changes, such as expansion or contraction, depending on the temperature change. Glass may also soften or melt depending on the temperature, but it will not produce combustion byproducts like wood.
Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning. Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.
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.
Rottening of wood is a chemical (breakdown) reaction
no, breaking wood is a physical change.If the wood was burned, that would be chemical change

When you burn wood a chemical change occurs.
A physical change because the chemical composition of the wood does not change.
Rottening of wood is a chemical (breakdown) reaction
Wood is a material. It is not a change.
no, breaking wood is a physical change.If the wood was burned, that would be chemical change
it is a chemical reaction because a new substance is formed when the wood rots
Chemical change
Chemical change
Chemical Because physical is when you change it your self
