why is it easier  for a person to swim in sea water than in fresh water?

Asked by arajeevshashank | 13 Nov, 2019, 06:58: PM
Expert Answer
It is because sea water contains more amount of salt as compared to river/fresh water as a result its density increases and hence the buoyant force increases which makes it easier to swim in sea water.
