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.
The most common example is the burning of a match or wood (or anything really).
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.
burning or tree or wood is an irreversible chemical change.
Burning wood is a chemical change - although, like most chemical changes it is accompanied by a physical change. Usually we reserve the term physical changes for things like erosion, melting, or evaporation where no change in composition occurs.
Burning logs in a fireplace is a chemical change. The wood undergoes combustion, which involves a chemical reaction where the wood reacts with oxygen to produce heat, light, and new substances like ash and smoke.
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.

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...
It is a chemical change.
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.
wood burning
It is a chemical change as you are altering the chemical structure of the wood.Burning wood is a chemical change. Although some might be confused on whether or not it is a chemical change it definitely is chemical change because when you burn wood, or mostly anything actually, a carbon dioxide gas is released into the air. As most might know a chemical change is when some type of substance reacts with another when in contact and it produces a new substance. In this case burning wood was created off of the burning chemicals in the wood, thus the carbon dioxide gas was released and exposed into the air.its chemical change definitely chemical changedefinite.It can be both actually because if you start a fire your self and do it or if it is a wild fire. :)its really physical.Chemical--new compounds are created. Example: glucose becoming water and carbon dioxide.Chemical change. Components in the wood combine with oxygen, releasing heat.chemical change;because once you have burnt it you cant make it a piece of wood again.Burning wood is a chemical change.its a chemical change, because you can not reverse itChemicalThe burning of wood is the oxidation of wood by combustion.Oxidation is a chemical reaction where (usually) oxygen reacts with a chemical to form other chemicals and gives off heat (an exothermic reaction).So the burning of wood is a chemical change. The resultant chemicals, (ash/soot/water/CO2...depending on the completeness of the reaction) are physically different to the wood, but the change is much more than physical.No, it is a chemical changeBurning wood is a chemical change.Burning wood is a chemical change because the reaction is not reversable and the end product is two separate chemicals.Burning wood is a chemical change because you are altering the CHEMICAL structure of the wood.it is chemical changeCombustion is a chemical process involving the oxidation. Burning wood is an example of this.ChemicalA chemical change. The composition is being changed and mass is lostChange of state from wood to ash can be described as physical change and burning of wood is through coming in contact with oxygen and hence it is both physical and chemical change.it is a physical changeA chemical change. The substances present before burning are altered to something else by the end of the burning.
