why is it easier to swim in salt water than in pure water
Answers
When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt. Because objects float better on a dense surface, they float better on salt water than fresh water.

This makes swimming a bit easier in salt water than fresh water. You never swim on top of the water like a boat.
