no its physical... i think.....
Chopping a piece of wood in half is a physical change because the chemical composition was not changed by doing so.
Yes, chopping is a physical change: the chemical composition of the molecules inside the wood remains the same. Burning causes the molecules in the wood to react with the air (mostly with the oxygen in the air), and the result is different compounds than before.
You're not changing the substance when you chop wood. Therefore, it is a physical change.
Yes just a physical change
Yes, it's the equivalent of chopping wood in half, which is also a physical change. Unlike chopping wood in half, this change is completely reversible.
when wood rots it is a physical change and not a chemical change.
A physical change because the chemical composition of the wood does not change.
Rotting wood is a chemical change.
Burning wood is a chemical change.
Carving wood changes the shape, but not the properties of the wood. Therefore, this is a physical change. In contrast, burning wood is a chemical change.
It is physical change. There are no chemical reactions taking place when you sand wood.
Wood decomposing is a chemical change.
Burning wood is clearly a chemical change.
Wood is a material. It is not a change.
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.
A chemical change.
both, the chemical changes alter the physical structure and properties of the wood.
Chemical Change :)
It is a chemical change.
Sanding wood is a physical change because it does not change the chemical composition of the wood.
Its a physical change
