Is cutting of tree a chemical change or physical change?

Cutting of trees is a chemical change since we cannot get back the original tree from the wooden pieces. It is Irreversible.


Physical change is the change of that matter where only the appearance or molecular arrangement of matter changes without changing its composition.

Examples: Boiling and freezing of water, melting of wax, mixing sand and grains, crumpling a paper bag, chopping wood etc.

Properties of physical change are as follows:

• Most of the physical changes are reversible. The original form of the matter can be attained.

• It is a temporary change and no new substance is formed.

• During a physical change, no energy is absorbed or released

• Physical change causes a change in physical properties such as shape, size, etc.

Chemical change: The change in which chemical properties of the matter change is known as chemical change.

During a chemical reaction, the chemical bonds between the molecules are broken and rearranged, and new bonds are formed resulting in the formation of new compounds.

For example, a photosynthesis reaction is a chemical change as carbon dioxide and water in the presence of sunlight and chlorophyll to give sugar molecules and oxygen as a product. Here, sugar once formed cannot be converted back to carbon dioxide and water easily. As a new compound is formed from the reaction between water and carbon dioxide, it is a chemical change.]
