It is the oxidation of the elements of the chemicals that make up the wood - which are various organic compounds. These are released into the atmosphere as carbon dioxide, water vapour and oxides of other elements and compounds.

Burning is an oxydation reaction so a chemical change.
Unfortunately, it is not a physical/reversible change, as combustion causes chemicals to change their bonding. A simpler example than wood would be glucose (the same reaction as in respiration): C6H12O6 + 6O2 --> 6CO2 + 6H2O This reaction is not reversible.
1.burning of wood 2.burning of magnesium in air 3.making curd from milk 4.heating sugar how come is these are 4 example
there are two types of change. the first one is the physical change. the form or appearance of the substance is change but the chemical properties of the substance is not changed. example, water evaporates into the air, that is a physical change because from liquid, water changes into gas but it then comes back to water as rain. the other one is chemical change wherein the chemical properties of the substance is changed. example is burning of wood. wood is burned and turned into charcoal. the chemical properties of wood is different from the chemical properties of charcoal and charcoal is another substance.
Combustion (burning) is a chemical change.
Burning wood in the fireplace is an example of a chemical change because the wood undergoes a chemical reaction to produce heat, light, and ash. This change is irreversible as the wood is transformed into new substances during the process.
Burning wood. When the wood is burned, it becomes black.

Burning is a chemical change.
The most common example is the burning of a match or wood (or anything really).
It is a chemical change.
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
wood burning
Burning wood is an example of a chemical change. The wood undergoes a chemical reaction with oxygen in the air to produce new substances such as carbon dioxide, ash, and water vapor.
yes charring of wood is chemical change
