The paper can be uncrumpled. There was no chemical change that occurred, so its basic molecular structure is still the same.

∙ 8y agoCrumpling is not a chemical change because the chemical nature of the paper remain unchanged.

Does the weight of a piece of paper change if you crumple it up?
No it doesn't change at all! Crumpling up the paper only changes the shape it but its weight stays the same.
Which form of energy is produced when paper is burned?
Thermal and radiant energy.
Why doesn't paper burn when in contact with metal?
The metal absorbs the thermal energy before it can build up in the paper enough to ignite. The paper will eventually burn when the metal itself absorbs enough energy to ignite the paper.
How is energy transferred from your finger to the paper boat?
If you make a paper boat move by pushing it, you are transferring mechanical energy, with the force of your finger. Such a transfer of mechanical energy is called "work" in physics.
What kind of energy is paper?
cool stuff
Does the weight of a piece of paper change if you crumple it up?
No it doesn't change at all! Crumpling up the paper only changes the shape it but its weight stays the same.
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.
what would writing down on paper be fore energy conversion/transformation?
A pencil would contain kinetic energy while it is moving, potential energy because it could be dropped and release energy that way...Anyone else agree???
What is a example of physics?
Water evaporating, crumpling or cutting paper, and inflating or deflating anything are all physical changes. Also water turning into ice is one.
Why is it hard to crumple a full sheet of paper with one hand?
It may or may not be hard, depending on your hand size and strength. Since the paper is bigger than most hands, some people have difficulties crumpling them. I just half crumple a sheet and throw it away.
What are some examples of a phyiscal reaction?
water turning to ice... water turning to vapor. candle wax turning from solid to liquid and then solid again... crumpling a paper is a physical while burning it is chemical...
What are some physical changes of silver?
· 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
Does paper absorb heat?
Depending on the source of the heat energy: -A darker piece of paper would absorb more energy from light sources, then a white piece of paper. This is due to the fact that the white piece of paper would reflect most of the light energy, whereas the dark paper would absorb that energy. This light energy can then be converted into heat energy, leading the dark paper to have more heat energy then the white paper -Heat from a source such as hot water being poured on the paper, would not lead to any color related heat difference
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.
Does paper have energy?
yes it does
Where does energy come from when paper burns?
Well think, if you burn a piece of paper, then energy is involved. Chemical energy is taking place when you burn a piece of paper. However, two more types of energy are also taking place. Thermal and radiant energy are also taking place because the fire burning the paper creates light (radiant energy) and it also gives off heat (thermal energy).
Why does paper shrink when you crumple it up?
It doesn't really shrink. But since you keep crumpling it just seems smaller because it's not flatened out any more. Also it almost feels softer this is because it has no more real drawing surface.
