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.
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.
Its a physical change
this is a physical change
said pop_singer17@yahoo.com...it is called a physical change because its just only a wooden stick and it doesnt change in color, texture,or substance. .just only in size...
Lighting A Match
No, charcoal is made by burning wood in a furnace.
chemical change.

Combustion (burning) is a chemical change.
Chopping wood for a fire is a physical change because the wood's size and shape are altered. Burning the wood is a chemical change because it undergoes a chemical reaction to produce heat, light, and other byproducts.
Because burnning wood is using energy but breaking is using forces. When wood burns, it's not wood any more. It turns into smoke, ash, and (maybe) charcoal. When you break wood, it's still wood. When you change something into a different substance, that's a chemical change.
Heat, smoke, and charcoal.
burning of 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 of wood is a chemical change as it produces heat and cutting it into small pieces is a physical change as there is a change in shape and size.
The chemical change is the burning wood because the products, carbon dioxide, water, ash, and soot, have different physical and chemical properties. The other changes are physical changes because the physical and chemical properties of the substances did not change.
The match burning and leaving a charred stick of wood is a chemical change. This is because the chemical composition of the wood is altered during the burning process, causing a new substance (char) to be formed.
