Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
of course it is a physical change, cutting paper does not change the paper, except change the shape. The paper does not change chemically.
Wadding a piece of paper is a physical change because the only thing about the piece of paper that is changing is its shape, not its chemical composition. You aren't changing how the atoms fit together in compounds, only where the particles exist in space in relation to each other.
it is a chemical change because a piece of paper can't be changed back into one piece of paper .
No, it is a physical change as no new chemical substance is formed.
Physical- it is still a piece of paper. It can be unwadded. But if you burned it (a chemical change) it is no longer paper, and you cannot unburn something.
its physical change you dumb people
physical
It can be a physical change because no new substance is formed and no heat is generated.
chemical change
It is a physical change because it is still a sheet of paper.
Yes! Burning anything is a chemical change because what was burned is now turned in ash, carbon, or some other type of material that is wasn't before, thus a change!
physical because he water can be gotten back out of the paper towel (drying out).yes
NO, it is a chemical change, because it cannot be reversed.No because it changes shape color Android more so its a physical changeBurning of paper is not a physical change. It is chemical change as ash is formed in the process which is new compound and oxides of carbon are also released during the process. By the definition of chemical change, we come to know that during chemical change a new substance must form. These changes are irreversible in nature.Yes because once you burn a piece of paper you just simply cannot turn it back to a blank sheet.
Physical one.
It is a physical change because it is still a sheet of paper.
The torn sheet has undergone a physical change, the burned sheet has undergone a chemical change, and the crumpled sheet has undergone a physical change.
Nope. It has undergone a chemical change, and is no longer paper.
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
Depending on the experiment, there will be a series of physical and chemical changes.
Not necessarily. This only happens in decomposition reactions, where energy reacts to break apart a compound. In, say, a synthesis reaction, sodium and chlorine combine, but don't leave a waste product. A physical change differs from a chemical change in that the product is the same substance, while in a chemical change it forms a/some different substance. Think about ripping a sheet of paper-is it still paper? If you burn the sheet of paper-is it still paper
Tearing paper is a simple physical change; you are taking a whole and dividing it without changing its chemical composition. Burning paper is a chemical change; the paper chemically reacts with oxygen in the air in the presence of heat; oxidation.
Yes! Burning anything is a chemical change because what was burned is now turned in ash, carbon, or some other type of material that is wasn't before, thus a change!
If the sheet is turning into a pillowcase, it would be a physical change. The sheet is not changing anything but its shape to become a pillowcase, and it most likely can be reversed to turn back into a sheet.
These are chemical reactions (changes).
physical because he water can be gotten back out of the paper towel (drying out).yes
Papermaking is not one single unit operation but a series of operations some of them such as pulping and bleaching etc. are chemical change while sheet formation, pressing, drying etc. are physical change.
