When crumpling a paper, the kinetic energy of your hands is transformed into mechanical energy as you apply force to crumple the paper. The mechanical energy causes the paper to deform and store potential energy due to its compressed state. Frictional forces also generate some thermal energy in the process.
Crumpling is not a chemical change because the chemical nature of the paper remain unchanged.
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

What are the energy transformations for a paper shredder?
The energy transformations for a paper shredder involve electrical energy being converted into mechanical energy to power the shredding blades. The mechanical energy is then used to cut and shred the paper, resulting in kinetic and thermal energy as the paper particles are produced and any heat generated from the process.
Does the weight of a piece of paper change if you crumple it up?
No, crumpling a piece of paper does not change its weight. The weight of the paper remains constant regardless of its shape or condition.
What happens when a paper is crumpled?
Crumpling a paper causes its fibers to bend and fold, disrupting its original structure. This can weaken the paper and make it more prone to tearing or wrinkling. Additionally, the surface area of the paper increases due to the crumpling, which can affect its appearance and texture.
What 4 examples of physical change?
Melting of ice into water. Dissolving sugar in water. Crumpling a piece of paper. Breaking a glass bottle.
How can you make a piece of paper fall as quickly as possible?
Crumple the paper into a tight ball before dropping it. The increased surface area and air resistance of a flat sheet of paper slowed its fall, and crumpling it reduces both, allowing it to fall quicker.

Is crumple a physical change?
Yes, crumpling paper is considered a physical change. It involves a change in the shape or form of the paper without altering its chemical composition.

Melting of ice into water. Dissolving sugar in water. Crumpling a piece of paper. Breaking a glass bottle.
Is crumpling a sheet of paper a physical or chemical?
Crumpling a sheet of paper is a physical change because it does not alter the chemical makeup of the paper. The paper still consists of the same materials and compounds before and after crumpling, but its physical shape has changed.
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.
Is crumpling a sheet a paper a physical or chemical change?
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
The best way to slow down a falling piece of paper?
The best way to slow down a falling piece of paper is to increase air resistance by crumpling the paper or increasing its surface area by attaching a parachute-like object to it. This will create more drag force, slowing down the paper's descent.
How do you make a falling piece of paper stay in the air longer than a flat piece of paper?
By crumpling the paper into a ball or folding it into an origami shape, you create more air resistance which slows down the paper's fall, making it stay in the air longer than a flat piece of paper. The irregular shapes increase the drag force acting on the paper, resulting in a slower descent.
