It is a chemical change. A physical change to the log would be, for example, cutting the log in two. When it burns, it turns into CO2 and H2O, so it can't be turned back into a log.

Is burning a log a example of chemical or physical changes?
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.
Is cutting a log into boards a physical property chemical property chemical change or physical change?
It is a physical change, because the wood is still wood but it is in a different form
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Because burning a log in a fireplace involves a chemical change and sawing a log in half only reguires a physical change.
Is cutting a stack of wood from a log a chemical change?
No, it is a physical change. If you think about cutting the wood, the pieces will be smaller than the log, but they will have all of the same properties as they did when they were put together. An example of a chemical change is burning the wood. The act of burning it would be a chemical change since it is converting the wood into carbon and water vapor.
Is burning log chemical change?

How do you know a chemical change takes place when a log burns?
Burning is a chemical process: the nature of the initial material is changed.
Why does burning a log in the fireplace involve a chemical reaction while sawing a log in half does not?
Because burning a log in a fireplace involves a chemical change and sawing a log in half only reguires a physical change.
Is cutting a stack of wood from a log a physical or chemical change?
Do the logs change from wood to some other substance? No, so it has to be a physical change.
Is sawing a log chemical reaction?
No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.
