No, it is a physical change. Burning the firewood would be a chemical change.
no its physical... i think.....
Burning wood is a chemical change.
Chopping an onion is considered to be a physical process. Chopping an onion is not a chemical process because it does not change the chemical composition.
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.
It keeps us warm when we burn firewood and it is the gas that we fuel our cars with.
I dont nkow

It is a chemical change. The wood, once burned, can't be restored to its original composition

One of the things an axe is made for is chopping down trees in the woods. Axes are also used for chopping firewood. However, if we don't own the property, we would need to get permission from the owner before chopping down any trees.

It is chemical because the nature of the chemical has changed.Physical changes including chopping, grinding, dissolving, melting, freezing, and boiling. An omlette cannot be turned back into an egg. The egg protein has changed its chemical nature. Physical change alters the form or appearance of a material without changing the chemical composition.
