Guest Posted April 15, 2008 Report Share Posted April 15, 2008 A plastic bowl containing a lump of metal is floating in a tub of water . I remove the lump of metal and drop it into the same tub of water. Does the water level rise, fall, or remain the same. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 15, 2008 Report Share Posted April 15, 2008 It really depends on the density of the metal. a heavier but smaller metal will rise the water more when in the bowl than when in the tub. a lighter and bigger metal will do the exact opposite.

0 Guest Posted April 15, 2008 Report Share Posted April 15, 2008 water will rise. IF the metal happens to be lighter than water, then the metal will float and displace the water by however much of the metal is below water. If it's heavier, than it will rise by the volume of the metal. A 3" cube of iron will make water rise same amount as a 3" cube of gold. Density doesn't matter UNLESS you're dealing with a buoyancy issue. Quote Link to comment Share on other sites More sharing options...
0 akaslickster Posted April 15, 2008 Report Share Posted April 15, 2008 Is the answer definitely one of the three choices only?? Quote Link to comment Share on other sites More sharing options...
0 itachi-san Posted April 15, 2008 Report Share Posted April 15, 2008 the water level will lower because when above water, the weight of the metal is taken into account, now in the water only the volume matters. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted April 15, 2008 Report Share Posted April 15, 2008 If it's heavier, than it will rise by the volume of the metal. No, the water level will fall. See the explanation in the link below. This one has been done before. A search for "water +rise" leads to this thread. Quote Link to comment Share on other sites More sharing options...
