Detailed Solution

The above statement is true.
●        The burning of wood is considered a chemical change while cutting a piece of paper into small pieces is considered a physical change.
●        When a substance undergoes a chemical change, its chemical properties are changed before and after the reaction by the breaking of any chemical bond at the molecular level. That is after burning wood becomes ash and the chemical properties of both wood and ashes are different.
●        When we are cutting a paper into small pieces only the physical appearance changes. Earlier it was large in shape, now it has become small in size, while the properties of the paper are the same before and after cutting.
