burning of wood and cutting of wood is both chemical and physical change take place?
Burning of wood and cutting of wood into small pieces are two very different processes. While burning of wood is both a physical and chemical change, the cutting of wood into small pieces only a physical process.
Wood is basically carbon. So when wood is burnt, the carbon combines with the oxygen present in the air and is converted to carbon dioxide. Also, the unburnt carbon is converted into a black mass. This process also leads to the emission of smoke. Thus we can see that burning of wood is involving the formation of new chemical substances. Also, the overall shape and appearance of wood changes. So it is classified as both a physical and a chemical change.
On the other hand, cutting of wood into smaller pieces is only a physical process. No chemical change is taking place as no new chemical substance is being formed. Here only the size of wood is changing. So it is a physical change.
