Question

Explain why the hull of the ship sinks more in freshwater as compared to the sea water.

Answer 1

There is no denying the fact that the hull of the ship sinks more in freshwater as compared to seawater and the reason for the same can be discussed below.

1. The depth up to which the ship sinks in water depends on the magnitude of the buoyant force acting on the ship.
2. More the buoyant force, the lesser will be the depth of immersion of the ship in the water and vice versa.
3. Density of seawater is more than the density of fresh water because the seawater contains dissolved salts in it.
4. Buoyant force on the ship in freshwater will be less than the buoyant force on the ship in seawater because buoyant force is directly proportional to the density of the fluid.
5. Due to lesser buoyant force in the case of freshwater, the hull of the ship sinks more in the freshwater as compared to seawater.
