Question

Why is it easier for you to boat in saltwater than in freshwater?

Answer 1

1. According to Archimedes' principle, the force of buoyancy is given by:
2. Buoyant force=$\rho gv.$
   1. where $\rho$denotes the density of the fluid.
   2. $g$ denotes acceleration due to gravity.
   3. $v$ denotes the volume of liquid displaced.
3. 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.
4. Therefore due to an increase in density of the fluid, upward Buoyant force will increase due to which object will float better in salt water.

Hence, it is easier to float in salt water than in freshwater.
