Yes, a coin does sink slightly faster in pure water than it does in sea water. The dissolved salts in sea water make the water denser, and as a result, objects immersed in sea water will experience greater buoyancy than they do in fresh water.
the sea water contains more salt. the pure water do not contain salt. the density of sea water is more than density of pure water. as there is more salt in sea water it is corrosive against the metals like aluminium. the pure water is not corrosive in nature. sea water is harmful for drinking. pure water is good for drinking.
You use distillation. Boil water and catch the subsequent steam. The steam will not contain the salt, which does not evaporate. Condense the steam and it will be pure water: 2 hydrogen, 1 oxygen.Read more: How_do_you_separate_water_from_sea_water
No.
Sea water has a lower freezing point than pure water due to the presence of salts, which lower the freezing point of the water. This means that sea water will freeze at a lower temperature than pure water.
no
I would imagine that the sea water would have to run through a water purifier.
Crystalisation
Yes, sea water has a higher density than pure water due to the presence of dissolved salts and minerals. The higher density of sea water allows objects to float more easily in it compared to pure water.
