Because the paper undergoes a chemical change. When it is done it no longer is regular paper it is a whole different substance. Flammabilty or the ability to burn is always considered a chemical change.
If you have a post it note, tear it in half. Does it stay the same? Yes. Now burn a post it note. Does it look the same? No. Is it still a post it note? No. It is now ash.

∙ 12y agoit shouldn't be a physical change because heat is envolved during the process. it is a chemical change because it gives out heat, a different smell, and gas is produced during the process. There is also a colour change.

∙ 13y agoBurning of paper produces new compounds including water, carbon dioxide, carbon monoxide, and carbon.
It also consumes other compounds such as oxygen and the various carbon-based compounds in paper.

∙ 6y agoyes because the paper turns to another form aka ash
Yes.
Yes. When anything burns it is a chemical change.
Yes, anything burning is a chemical change.

∙ 12y agoits not just changing shape it is changing the whole chemical make up it is also no longer wood it is ash. these are made of different things

∙ 11y agoBecause you cannot undo a burn/fire damage, versus un-crumpling it.
Wiki User
∙ 10y agoThis is a permanent change: paper is gone, can't get it back from ashes.

Is Burning wood is an example of physical change.?
I think you mean "Is burning a paper a physical change?" Burning a paper is not a physical change. It is a chemical change. Because you can't turn the ashes of the paper into a normal paper again. Examples of physical change: Cutting a paper, sharpening a pencil, writing on a paper... Examples of chemical change: Rotten egg, Rusted steel, molded bread...
How does burning become a chemical change?
Burning is a chemical change as when we burn anything eg paper a new substance is formed known as ashes. Therefore when a new substance forms it is known as chemical change. By Annika Khullar
Is sand flowing through an hour glass an chemical or physical change?
It is not really a change, at all. Sand is moving from one spot to another. If it truly had to be categorized, I would put it under a physical change. A physical change would be a change in an object you can see with your eyes. However, the chemical makeup of that object does not change. In other words, no new chemical is formed. For example, water may freeze or evaporate, but the chemical makeup of water, no matter what state it is in, is H2O. A chemical change would would result in the formation of one or more new chemicals. For example, burning paper is a chemical change. You have paper and fire, and when you burn the paper up, it gives off CO2, and charred paper, which is different from regular paper.
How can you tell that a burning piece of wood is chemical change?
Because you can't put it back together. Imagine burning a piece of paper, there is no way that you can get that piece of paper back. Burning that piece of paper was a chemical change because you changed the chemical properties of the paper. Crumpling or cutting the paper doesn't change the molecular structure of the paper, so it is a physical change.
Is paper making wood a physical or chemical change?
making paper from wood is a what change
Is a paper burning a physical or chemical change?
its a chemical changePaper being burned a chemical change as it is irreversible.Chemical change.chemical.... do work son!ChemicalIt is chemical change, a.k.a a chemical reaction.Burning a piece of paper is a chemical change
Is a burning paper a chemical reaction?
Yes it is a chemical change because when you burn paper it cannot be reversed. If it had been a physical change then you would have been able to reverse what you have done to the paper, by turning it back to its original state.
Does a physical or a chemical change?
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
Is cutting a circle out of a piece of paper a chemical change?
No. It is a physical change because there is no change in the chemical composition of the paper. If you were to burn the paper, that would be a chemical change called combustion, which would turn the paper into carbon dioxide and water, with the release of heat.

How can you physically change a piece of paper?
In order to change the physical properties of an object, one must alter the 'format' of an object. An alteration of the physical properties is only a shift in the way an object can be described, not in the chemical composition of the product. In context a piece of paper could have its physical properties changed by being burned, being shredded, or by being submerged in water.
Is gasoline's ability to burn a chemical or physical change?
Neither - but when it does burn it's a chemical change.
What would NOT mean that a chemical change has occurred?
When chemical change has occurred, it means that the object has become something that it will be forever until changed again. For example, when you burn paper, it has become something new, a new substance. That paper has become ashes and will never be paper again.
Is burn a chemical or a phhysical change?
Chemical.
When you burn paper what happens?
Burning is a chemical change. When paper burns, various organic compounds within the paper react with oxygen in the air to make products. The products represent a new form of matter, which is a characteristic of a chemical change.
