tearing a piece of paper is a physical change because when you rip it,it is still a piece of paper but lets say that u burn a piece of paper its a chemical change couse you cant change it back to wood again
Because it is still paper but it looks different than before.
That help?
Yes, because you are using sheer willpower to change the paper. Making you the cause of the change.
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.
Some examples of physical change include melting an ice cube, chopping wood, and breaking a piece of glass. Additional examples include tearing a piece of paper, combining water and sand, and boiling water.
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
Tearing an aluminum foil is a physical change. This will only alter the physical features of the foil and not have any effect on the chemical composition.

Physical. It's still aluminum foil.
ANSWER:Its a physical change. If you burned it and it became ash, its a chemical change. Physical change means it made no change on a molecular level. Its still paper, just in two separate pieces.It is a physical change, as the chemical property of the paper remains unchanged.
Tearing paper does not directly affect the composition of the paper's molecules, or its mass. You can recycle the paper, and end up with a piece of paper again. For some types of paper, simply wetting it, connecting the pieces, and drying it again would create the same size sheet of paper.

· Absorption of water into a towel · Crumpling a piece of paper · Pulling copper into a thin wire - a change of shape, but not a change of composition · Cutting a material such as wood · Tearing a piece of tin foil
no it is not a physical change because folding a piece of paper does not chemicaly change it.
