No. The wood that you made the chair out of is still wood, so it is just a physical change.
No, changing the size and shapes on a pieces of wood is not a chemical change
depending on size and what kind of wood ash wood is heavy
a physical change can be reversed a chemical one can'tA chemical change is when a new substance, with new and different properties, is produced. The identity of the original substance is changed. In contrast, a physical change is when one or more of a substance's physical properties have simply been altered; no new substance is produced.
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
It is the breaking of chemical bonds, and therefore is releasing chemical energy.
Wood has chemical energy that can be converted into light by burning the Wood. Nitroglycerin has chemical energy that can be converted into sound by shaking it (Don't try this at home!).
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.
when wood rots it is a physical change and not a 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
If you change a peice of wood into a chair or a table that is known as woodworking. If you change a lump of metal into a chair or a table it is known as iron mongery
