Combustion is a chemical change, so the burning of a tree will be a chemical change.
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.
burning of tree or wood is an irreversible chemical change

The flow of this liquid is a physical phenomenon; but the formation of this "syrup" is a chemical change.
no because of the law of conservation of mass it states that no matter is created or destroyed in any chemical or physical change
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.
it's a physical change because no new substances were formed.
Yes, chopping a tree is a physical change because it alters the physical appearance of the tree by breaking it into smaller pieces, but it does not change the chemical composition of the tree.
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.
it is a physical change because its chemical composition does not change and no new substance is formed
