Hammered Copper Sink

Why does copper sink in water?

with one comment

Is it because it is denser than the water and that less denser things float on denser things (particles are closer together for denser things)? What else are factors?

  1. This is a varying situation. The density of the sample (Cu) when placed into the solvent (water) will help to determine whether the sample will remain on the surface of the water or sink to the bottom of the container. Odd enough to imagine, you can actually have a certain solid sample that has the proper density to float partially underwater (such as half-way between the surface and the bottom).

    Other factors that will affect this are depth of the water (pressure that it is placing on the object), as well as the surface area of the sample. A flatten piece of copper may float while the balled-up version of the sample will sink. This has to do with the force being applied on the sample by the water versus the force applied on the sample by gravity.
