Burning of wood is a chemical change because in burning new substances are formed as
Wood + Oxygen —> Charcoal + Carbon dioxide + Heat + Light
But cutting it into small pieces is physical change because no new substance is formed. We can only reduce the size of wood.
When we burn wood, a new substance, coal, is formed. Therefore, it is a chemicalchange.
