Question

A ship enters from an ocean to backwater, will the ship sink or rise more?why?​

Answer 1

Explanation:

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.

Answer 2

When a ship will enter from an ocean to the backwater it will sink more

• Since not all the salts are dissolved in the fresh water, a volume of fresh water weighs less than the same volume of seawater.
• As a result it is required by the ship to displace more fresh water in order to balance its weight. When the ship tries to balance its weight, in doing so it sinks.
