Not really. The crystal structure of the metal may be rearranged slightly, but density won't change. When we make aluminum foil, the finished foil, which has been rolled very thin, weighs what the plate that it was made from weighed before it was rolled (stretched) out.
It will increase the total volume, but it will hardly affect total mass. Remember the definition of density as mass / volume.
Yes, the overall density would be less than if the rod were pure metal.
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.
Low Density a Metal?NO!!!!
Every metal has a density.
The density of the metal in the crushed can remains the same as the density of the metal before it was crushed. Density is an intrinsic property of a material that does not change with physical alterations like crushing. So, the density of the metal in the can will not change due to the crushing process.
An air bubble clinging to a metal object would decrease the overall density of the object. The presence of the air bubble adds volume without contributing much mass, leading to a lower density calculation.
If you cut a metal in half, each half will have the same density as the original metal, so the density of each half will still be 8.4. The density of a material does not change when you cut it into pieces.
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase
Indeed yes. Density is defined as mass per unit volume. If all the mass were concentrated in one lump, your boat would no longer float. If the metal walls of the boat were a little thinner, you'd have more boat volume, and lower density.
The density of the metal in a crushed can remains the same as the density of the metal before the can was crushed. The mass of the metal remains constant; only its shape changes when the can is crushed.
