No. It must go through a chemical reaction to be a chemical change.
In example, burning a candle: Is it still the same thing before and after you lit it? yes.
So if in the process of burning the leaf it went through a chemical reaction, then it would a chemical change. Since only its appearance changes, not its chemical structure on the molecular level, it is only a physical change.

∙ 13y agoBecause when you burn a leaf, it is changing its chemical composition. It's no longer celulose (and the other components), but it is converted to carbon dioxide (CO2) and water in the form of vapor.
Wiki User
∙ 15y agoYes as the mollecular structure has been altered and new substances are fromed
Wiki User
∙ 13y agoYes, all types of burning are chemical changes because the chemicals are reacting and becoming a different chemical.

Is hammering metal into a flat sheet physical or chemical change?
A physical change means converting how an object looks or feels. Water changed into ice or water would be a physical change. Breaking, bending, melting, evaporating are all physical changes. A chemical change would be changing an object into something you can't change back. Taking bark off a tree (physical) and burning it is a chemical change. Chemical change means burning, rusting, and combustion. I hope this helped. Nossy
When you hydrochloric acid and chalk together is it physical or chemical change?
Chemical physical is something like... a dent in metal, a cut in a tree, etc chemical is a reaction like ^acid on chalk or wood burning
Is leaves falling from a tree chemical change or physical?
physical
What is a chemical change cutting paper mashing potatoes chopping down a tree burning wood mixing paint?
Burning wood is a chemical change.
Is breaking of a tree branch a physical or chemical change?
Yes, it is undoubtly physical itself. The cause of easy breaking eg. after chemical detoriation of its fibrous structure by molds can be chemical. The force by which it's breaking (wind, gravity) is physical however.
Is a tree burning a chemical or physical change?
Combustion is a chemical change, so the burning of a tree will be a chemical change.
Is a tree being burned a chemical or physical change?
burning of tree or wood is an irreversible chemical change
Is burning a tree chemical or physical?
well its both because...it's a chemical change because when the tree is burning it's letting oxygen and carbon oxide in the air. It's also a physical change because if that tree is sharing roots with another tree that other tree root will become damaged and will sooner or later will be dry rotted and the tree will fall over(it can also damage the grass around it).
Is a tree that caught on fire a chemical change?
burning or tree or wood is an irreversible chemical change.
If you cut down a tree do you release the carbon that is stored in it?
Cutting a tree is a physical change. To release the carbon, there has to be a chemical change. Burning or rotting will release the carbon.
Is a tree burning into gas a chemical or physical change?
It is a chemical change since it isn't a tree or even any wood of any sort since the wood has combined with oxygen. If you would cut a tree down and make wood planks, it would still be wood (physical).
