Crushed (crumpled) paper occupies more space than folded paper, and better resists being compressed, because the paper material contains irregular folding against the grain, or strength of the paper. Part of the ball consists of flat surfaces and part as "columns" that resist being further crushed. The paper's relative stiffness will determine the actual difference in compression resistance.
Most of the volume of a paper "ball" is "trapped" air spaces between the crumpled folds.
A similar use of the strength of the material can be demonstrated by creasing a piece of paper into a fan consisting of multiple pleats, with a cross-section having a sawtooth shape. This pleated sheet will resist deformation (bending) to a much greater extent than the unfolded paper sheet.

Why does a crushed paper fall down faster than a plain paper?
A crushed paper falls faster than a plain paper because the crushed paper has less air resistance due to its folded and crumpled shape. This reduces the surface area exposed to air resistance, allowing it to fall more quickly.
Why does air occupy more space when heated?
When air is heated, its molecules gain kinetic energy and move faster, causing them to spread out and occupy more space. This increase in volume is due to the expansion of air molecules as they collide with each other and the walls of their container, leading to an increase in pressure and volume.
If an object takes up more space than another object what will it have?
If an object takes up more space than another object, it will have a larger volume. This means the object has more capacity to hold substances or occupy a greater area.
If bread is crushed does its density change?
No, the density of bread remains the same when it is crushed. Density is a property of the material itself and is not affected by changes in shape or size. So, crushing bread will not change its density.
What happens when you fold a piece of paper 7 times and then crush it with a hydraulic press?
When you fold a piece of paper 7 times and then crush it with a hydraulic press, the paper will likely break or tear due to the immense pressure applied by the press. Folding the paper multiple times weakens its structure, making it more susceptible to damage when crushed.
