Question

It is easier for a swimmers to swim in sea water thaen in fresh water how?

Answer 1

It is easy to swim in sea water.

Explanation:

Because of the extra salt in salt water, it is denser. therefore you float better.Because salt water has a higher specific density than fresh water. (Specific gravity of water is like the density of an object.) Imagine floating in fresh water that has a lower specific gravity, like frothy white water in a river. It is very hard to stay above the surface in that water. So you float higher in water that has a higher specific gravity. Another way to put this is that the lower the relative density (your density divided by the specific gravity of water) the easier it will be for you to float. If the Relative Density is greater than one, the object will sink. If it is less than one, the object (you, for example) will float. so much salt lifts you up. try the paper clip and paper towel trick sometime In other words Salt water is heavier than fresh.
