Answer» The burning of wood leads to the formation of new substances like ash(carbon), carbon dioxide GAS, water vapour, heat and LIGHT. This change is IRREVERSIBLE and hence a CHEMICAL change.While cutting wood into smaller pieces is a physical change as there is no change in the ORIGINAL composition of wood. Also, no new substances are formed.
