Suppose the same slab of ice were floating on salt water, which is denser than fresh water. The answer to the preceding question would then be: (a) greater. (b) less. (c) the same. What is the mass density of an object, which weighs 322.00 lbs and displa...
Cold, salty water is denser than warmer, fresher water, and can sink beneath it, which can influence the movement of ocean water (currents). How Much Is Salt in the Ocean? According to the USGS, there is enough salt in the ocean so that if you removed it and spread it evenly over...
than it didbefore the ice appeared.Of course,when this ice melts,it will tend to decrease the salinityof the surrounding water.In the Weddell Sea,off Antarctica,the densest water in the oceans is formed as a resultof this freezing process,which increases the salinity of cold water.This ...
" magnesium sulfate, in their water. Denser water means more buoyancy. You've probably seen the same effect when you've been swimming at the beach: it's much easier to stay afloat in salt water than fresh water.

Or the whole genre of grindcore, predicated on the principle of compressing what could conceivably be a six-minute song if it were performed by, say, Suffocation, into a denser-than-Iridium thirty seconds? OK, these are valid points, but not the right points. Metal over-the-topness is ...

or if it is less dense. When you put some handful of stones into a bucket of water, all the stones will sink. The stones are denser than the water and hence can displace the water easily. If an object has to float, it has to displace the amount of water same as that of its weig...

the layered mixture, and keeps out oxygen from the atmosphere.The fresh water floats on a denser layer of saltwater.Underneath this is a layer of poisonous hydrogen sulfide, produced by bacteria living in the water.Underneath this layer is anoxic seawater-water that does not contain any oxygen....
