Yes, cutting a rope is a physical change because it alters the physical form or appearance of the rope without changing its chemical composition.
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
Cutting a copper wire is a physical change because the chemical composition of copper remains the same before and after cutting. No new substances are formed during the process, so it is considered a physical change.
Cutting a log into smaller pieces would be an example of a physical change. The wood is still wood, just in smaller pieces, so the chemical composition remains the same.
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
grinding any substance would by a physical change, because they are still that object
Cutting the bar in half, melting it, heating it, grinding or filing it, drilling holes in it- and it is still steel. It has not changed chemically.
Yes, cutting a rope is a physical change because it alters the physical form or appearance of the rope without changing its chemical composition.
Grinding mercury and iodine is a physical change because the substances themselves are not being altered on a molecular level. The grinding process simply affects the physical state or appearance of the substances, but does not cause a chemical reaction to occur.
Cutting wood into 10 pieces is a physical change because the wood's chemical composition remains the same. The change only affects the physical state of the wood by breaking it into smaller pieces.
No, cutting your finger is a physical change, not a chemical change. Chemical changes involve the rearrangement of atoms in molecules to form new substances, while cutting your finger only changes its physical appearance.
Cutting a string into two pieces is a physical change because the chemical makeup of the string remains the same. The process of cutting only affects the physical state of the string by changing its shape and size.
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
Cutting a diamond is a physical change because the structure and composition of the diamond remain the same before and after cutting. The physical change alters the shape and size of the diamond without changing its chemical properties.
It is a physical change because paper is still paper and its the same even if it has been cut. If the paper were say to get burned it would be chemical change because it is no longer paper and it has a different form.
Yes. You still have marshmallow at the end of the cut so it must be physical. If you burnt the marshmallow, that would be chemical.
Because the change in the bonds of the plastic while cutting it can never be the same again once cut. You could melt it back, but it would still be different.
