Is crumpling a sheet of paper a physical or chemical?
It's a physical change because it alters the physical state (size, amount, shape, etc) of the object. It is still chemically identical before and after the change, however the physical characteristics have been changed. A chemical change is one that alters the chemical composition of the item, for example the rust on a piece of iron is a chemical change because the new chemical composition is iron-oxide as opposed to iron.
Is coloring on a white piece of paper a physical change or a chemical change?
Coloring on a white piece of paper is a physical change because the color change is reversible and does not alter the chemical composition of the paper. The paper remains paper even after coloring on it.
Is tearing paper chemical or physical?
Tearing paper is a physical change because it does not alter the chemical composition of the paper. The paper still remains paper, just in smaller pieces.
When a piece of paper is torn into two pieces has it undergone a chemical change or a physical change?
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.
Is origami a physical or chemical change?
Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.
Is crumple a physical change?
To crumple, bend, or tear paper is a physical change. Because crumpling only changes something's shape, it is a physical change.
Is crumpling a sheet of paper a physical or chemical?

Is crumbling paper a chemical change?
Physical. You're not doing anything to alter the chemical structure of the paper. If you soaked it in ethanol and lit it on fire before crumpling it, that would be a chemical change.
Is tearing a paper a chemical or a physical change?
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.
Is cutting a paper physical or chemical change?
It is a physical change because it is still a sheet of paper.
tearing a piece of paper in half physical or chemical change?
Physical change
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 cutting paper a chemical?
No, cutting paper is a physical change, not a chemical change. The paper's chemical composition remains the same before and after cutting; only its physical shape is altered.
Is folding paper a physical change or a chemical change?
Physical.
Is folding paper physical or chemical change?
It is a physical change as the paper is still paper after you fold it.
Can you give 5 examples of physical changes and justify?
Melting of ice: Ice melting into water is a physical change because it only involves a change in state from solid to liquid, without altering the chemical composition of water molecules. Boiling of water: Water boiling into steam is a physical change as it involves the conversion of liquid water into water vapor, without any chemical reactions taking place. Crumpling a piece of paper: Crumpling a piece of paper is a physical change because it only alters the shape and appearance of the paper without changing its chemical composition. Freezing water: Freezing water into ice is a physical change as it involves the transformation of liquid water into a solid state without any alteration in the chemical properties of water. Breaking a glass: Breaking a glass is a physical change because it involves the glass shattering into smaller pieces, changing its physical appearance but not its chemical composition.
Is wadding a sheet of paper a chemical change?
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
