Yes. You can make a loaf of bread occupy less space by crushing it. This will crush its structure, which is filled with lots and lots of small spaces. With the material crushed together and the small spaces greatly minimized, there will be the same amount of bread as before, but in a much reduced volume. The density of the bread is increased. And haven't we all, at least at one time or another, crushed up a piece of bread and made it smaller and, therefore, more dense?

I'm wondering the same thing. I asked my teacher, and all she said was "NO NO NO NO"...

How does the density of the metal in the crushed can compare with the density of the metal before the can was crushed?
The density of the metal doesn't change when you crush a can.
How does the density of the metal in a crushed can compare to the density of the metal before the can was crushed?
No change. Crushing just pushes out air.
Does the mass of something change when it is crushed?
no its got the same amount of density therefore its mass if the same.
How does the density of the metal in the crushed can compare with the metal's density before the can was crushed?
It depends on what you're measuring: the density of the aluminum or the aluminum and the space inside the can. If it's the density of the aluminum only, it doesn't change much. If it's the density of the aluminum and the space inside the can, the density greatly decreases as you are getting rid of the air, and therefore the volume, inside. This also depends on if you are using your foot or a garbage compacter.
Why does changing shape of an object dose not change the density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.

What happens to the volume of a loaf of bread that is squeezed?
Of course. Like anything, when bread is crushed, its density increases. Anything that is crushed will have higher density in its crushed state. The only things that you can crush and NOT (permamently) increase their density are those that return to their original shape after being crushed. The increase in density is due to the fact that there is more bread in a smaller volume. When you squeeze the bread, you squeeze out some of the air, reducing its volume while maintaining its mass. Density = mass/volume.

How does the density of a crushed metal can compare to the density of the metal can before it was crushed?
The crushed can will have a density that is quite a bit higher than the density of the can before it was crushed. Imagine a box of empty aluminum beverage cans. It won't weigh much. If those same cans are crushed, they will weigh the same, but take up a lot less space. The density of the cans can be increased by crushing them. The cans might be said to have a low bulk density before being crushed.

Is it physical or chemical change when dough becomes bread?
Physical. This is so because it is not a change in energy, but a change in density, or mass.
How does the density of a metal in the crushed can compare with density of the metal before the can was crushed?
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase

A loaf of bread with a volume of 3000 cubic cm and a destinyof 2.0 grams per cubic cm is crushed in the bottom of a grocery bag into a volume of 1500 cubic cm what is the density of the mashed bread?
Density = (mass) / (volume)From the definition, we see that density is inversely proportional to volume.If the mass is unchanged while the volume decreases by a factor of 2, the density increases by a factor of 2.The new density is (2.0 x 2) = 4 gm/cc
What is the density of crushed concrete?
The density of crushed concrete varies depending on the gradation and quantity of impurities (e.g. asphalt and other) but can be estimated at 1900-1950 kg/m^3.
What can be substituted for flour WHEN breading food?
Panko Bread crumbs, Bread crumbs, crushed corn flakes
