Sawing a board in half is not an example of chemical change. It is an example of a physical change. Physical changes on a substance do not change the substance. When you saw a board in half, the two halves of the boards are still boards- they're not anything else.
The parts of the tree that burn are undergoing a chemical change. The ashes remaining may or may not have undergone a chemical change, depending on the the chemical bonding that the atoms in the ash had before the tree was burned.
Leaves falling from a tree is a physical change. It is a change in state or appearance without altering the chemical composition of the leaves.
The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.
The tree being struck by lightning is a chemical change because it involves a transfer of energy that can cause chemical reactions in the tree, such as burning or decomposition. This changes the tree's composition and cannot be easily reversed.
Breaking of a tree branch is a physical change because the chemical composition of the wood remains the same before and after the branch breaks. Only the physical appearance and state of the branch changes.
Combustion is a chemical change, so the burning of a tree will be a chemical change.
burning or tree or wood is an irreversible chemical change.

it is a physical change because its chemical composition does not change and no new substance is formed
Leaves falling from a tree is a physical change. It is a change in state or appearance without altering the chemical composition of the leaves.
no it is a physical change the tree did not change into a different thing it simply changed in size
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
First of all lets understand Physical & Chemical Change. Physical change can be reversed and the chemical properties of the two states remain the same. Chemical change cannot be reversed and the chemical properties of the two state are entirely different. Now lets get back to the question. Is growing a tree a physical or a chemical change. The growing of a tree requires chemical changes, primarily the conversion of water and carbon dioxide into cellulose and oxygen. So the growth results primarily from chemical changes.
Yes,Decaying Of Wood Is Chemical Change. Answered By Warfa
Lichen growing on tree bark is a physical change. The process involves the physical attachment of the lichen to the bark's surface, without any change in the chemical composition of the bark or the lichen itself.
