Problem 7

Consider an iron nail, which sinks swiftly in water due to its density. Even though ships are made of iron, they will not sink in water. A ship has a larger volume than a car. As a result, the buoyant force (which is proportional to the volume of the body immersed in the liquid) is significantly increased, resulting in the upward buoyant force. As a result, the ship's iron hull does not sink.

This is also owing to its shape. There is a hollow structure in the center of a ship. A ship's full volume displaces water to make room for itself when it is in the water. The volume of water expelled is more than the entire volume of the iron ship. As a result, the up push is more than the ship's weight, according to Archimedes' principle. Because of this, the iron ship floats in water.

Step 1.

Because iron is heavier than water, its weight is more than the weight of water displaced, and the nail sinks.

 

An iron ship, on the other hand, is built to carry more water than it weighs.

 

Second, because the ship is hollow and the empty space within contains air, the ship's average density is lower than that of water, allowing it to float.
