Give the scientific reason..
Why does a nail sink in water whereas a ship having a much bigger mass floats on the surface of water ?
Answers
due to less surface are nail dinky
where as ship has large surface area even though heavy so doesn't sink
As the density of an iron nail is more than that of water, the nail sinks in water. This is understandable. But a huge ship made of iron floats. This is because of its shape. A ship is hollow in the middle. When the ship is in water the entire volume of the ship, including the hollow portion, displaces water to make space for itself. The volume of water displaced is much greater than the volume of the iron ship. Hence, according to Archimedes' principle, the upthrust is more than the weight of the ship. That is why the iron ship floats in water.
In short, we can say that the shape of the ship makes its overall density less than that of water and hence the ship floats.
