no it is a physical change the tree did not change into a different thing it simply changed in size
A tree burning down and becoming ash
Ofcourse it does. All plants, algae and cyanobacteria perform photosynthesis, which is a chemical reaction. So answering your question, tree growth and for that matter all plant growth involves chemical changes.
burning or tree or wood is an irreversible chemical change.
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.
Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.
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.
Burning wood is an example of a chemical change because the wood reacts with oxygen to release energy in the form of heat and light. The other examples are physical changes: cutting paper, mashing potatoes, chopping down a tree, and mixing paint involve changes in shape, size, or state without altering the chemical composition of the substances involved.
by chopping it down! HAHA - Lexi
no ... physical
Burn it D:<

Combustion is a chemical change, so the burning of a tree will be a chemical change.
chemical change..... we just talked about this in science today and that is what my teacher said
