Question

A ship enters from an ocean to backwater. Will the ship rise or sink? Why?

Answer 1

Answer:

The floating of ship depends upon the weight of the ship balanced by the force of buoyancy or the upward thrust.

When the ship moves from the sea to the river the salinity decreases and the weight of the ship will be more which may result in the sinking of the ship.

To prevent this, there are air chambers in the ship which are filled with water to increase the weight.
