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.
A chemical reaction, and also a reaction in general.
the burning rate of paper actually depends on the type of paper because they all have different densitys which will affect the burning rate of each type paper.in conclusion there are different burning rates.
Although there are many different paper types, normal cellulose paper will burn at 451°F.
putting water in to the refrigerator to freeze it cutting wood dropping plates, or cups chopping fruits or vegetables tearing paper breaking items chewing pencils peeling potatoes
Yes. A change in shape took place. The changing of shape does not change any chemical properties of the cloth.
because burning of paper is a chemical change while tearing of paper is a physical change
Burning paper involves a chemical change where the paper is oxidized to create ash and smoke, releasing energy in the form of heat and light. Tearing paper is a physical change where the paper is physically separated into smaller pieces, but the paper itself remains unchanged chemically.
Tearing the paper - cannot be reversed. Once torn - the paper can never be identical to the original. Burning paper - changes the bonds of the paper molecules.
Tearing a tissue paper is a physical change because it involves a change in the physical state of the paper without altering its chemical composition. The other options, burning a match and baking a cake, involve chemical changes as they result in new substances being formed through chemical reactions.
Tearing paper is a physical change as you do not change what the parer is made of.
Tearing paper represents a physical and not a chemical change. Chemical bonds are not broken in this instance, but paper is physically separated (by force) from other paper.
A physical change. A chemical change would be, for example, burning clothes, or dissolving clothes.
No, tearing of paper is an irreversible change because once the paper is torn, it cannot go back to its original form as before tearing. The physical structure of the paper has been permanently altered.
Tearing paper is a physical change that is reversible. It can be reversed by taping or glueing the torn pieces back together. The paper retains its chemical composition after tearing, making it possible to revert back to its original state.
no
It is a physical change.
Psychical change because you're not changing the chemical make-up of the piece of paper, just dividing it. Think of it like cutting an apple. You can only cut it so many times before it's a chemical change.
