1C. If you are burning a log in the fireplace, what kind of change is the log going through?

Answer 1

When you burn a log in the fireplace, it undergoes a chemical change. This process involves the log reacting with oxygen in the air, resulting in the formation of new substances such as carbon dioxide, water vapor, and ash. The chemical structure of the wood is altered permanently during this process, distinguishing it from a physical change, which would not alter the substance's chemical composition.
