Burning a piece of wood in fire can be best described as a chemical change because the atoms in wood change their state.
O physical change because the atoms in wood are turned into a gaseous product.
chemical change because the atoms in wood and oxygen are rearranged.
O physical change because the atoms in wood are turned into black ash.

Chemical change because the atoms in wood change their state

Explanation:

Explanation: The chemical composition of wood varies from species to species, but is approximately 50% carbon, 42% oxygen, 6% hydrogen, 1% nitrogen, and 1% other elements.

When wood is being combusted in air(oxygen being the gas that rekindles the glowing splint), the chemicals are rearranged. Since about 50% of wood is carbon, C, the main chemical reaction going on here is C + O2 --> CO2. Of course, there are other chemical reactions too. But the formation of CO2 is the most common.

The heat added represents an energy change.
