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.
The metal's density should be the same. Crushing is a physical change and should not affect the density of the metal.
The density is less
There are many various types of Metals and metal alloys. Magnesium is one of the lightest metals. Aluminum alloys is next. Steel alloys and Lead and Gold are the heaviest metals.
That is not a reliable discrimination. Astatine and Radon have much more mass than the majority of metals. And Lithium and Magnesium are lighter than many non - metals.

Divide the mass by the volume to calculate its density. If its density isn't the same as an equal amount of pure silver, the coin has some other metal in it.The density test can be fooled if the coin was adulterated with other metals that average out to the same density as silver, however.
Metals heat up as electrical currents flow through them. Cold resistance is the metals resistance before it is operating. Hot resistance is the metals resistance after operating time has elapsed some.
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase
The density of metals is greater.
Yes Metals have a high density.
It varies. Many metal have high density. In fact, the metals iridium and osmium are the densest substances known to man. However some metals are light. Lithium and sodium are even less dense than water.

Yes, transitional metals do have high density.(This is due to the tightly packed crystal lattice of the metallic structure.)
you will have to determine the properties of your sample, and compare these with a table of properties of metals. Density is a good easy one to start with. But you could consider colour, softness and so on.
Gold has the highest density of the metals listed.
