All its substance goes gone it turns to ashes so it's not wood anymore and it becomes Chemical Change
A log is a mixture regardless of whether it is burning.

Although it has physical consequences, burning a log is a chemical change. The molecules of the log react with oxygen to form carbon dioxide, water steam, and many other products. A simple, fairly reliable test to tell the difference between physical and chemical changes is: Can the process be reversed rather easily? If the answer is yes, like dissolving salt in water, it is a physical change; if no, a chemical change.
Yes.
A burning log can reach temperatures up to about 600-900 degrees Celsius (1112-1652 degrees Fahrenheit), depending on the type of wood and conditions of the fire.
The observable change for burning a log is the production of heat, light, and smoke.

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.
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.

If you want to keep an olive log burning try putting olive oil on the log
The burning of a log in a fireplace is a chemical change, as the wood undergoes combustion to produce ash, smoke, and gases. The log is transformed into new substances with different properties, such as carbon dioxide and water vapor.
