All its substance goes gone it turns to ashes so it's not wood anymore and it becomes Chemical Change
The observable change for burning a log is the production of heat, light, and smoke.
When a log is burned, observable changes include the transformation of the log's solid structure into ash and smoke as it combusts. The log changes color, often turning from brown or gray to black as it chars. Heat is produced, and gases like carbon dioxide and water vapor are released into the atmosphere. Additionally, the size of the log decreases as it loses mass through the combustion process.

While burning a log, you will observe flames and smoke as the wood undergoes combustion. The log will gradually reduce in size as it releases heat and light energy. Eventually, you will be left with charred ash and embers.
Burning the log is a chemical change. All of the others are physical changes.
During the burning of a log, you can observe flames, smoke, and glowing embers. As the log burns, it will shrink in size and eventually turn into ash. The color of the flames and the intensity of the heat can vary depending on the type of wood and the conditions of the fire.
Burning a log results in the release of heat and light energy, as well as the production of ash and smoke. This process is a chemical reaction where the wood combines with oxygen to form carbon dioxide and water vapor.
A log is a mixture regardless of whether it is burning.
