When burning a log in the fireplace, the log undergoes a chemical change. This process involves the combustion of the wood, which results in new substances being formed, such as ash, smoke, carbon dioxide, and water vapor. The composition of the log changes fundamentally during burning, indicating a chemical transformation. In contrast, a physical change would involve alterations in physical properties without changing the chemical composition.
If you are burning a log in the fireplace, what kind of change is the log going through?
