why an iron needle sinks in water but an iron ship float in water
Answers
Answer:
The density of iron is more than the density of water, so the weight of iron is more than weight of water displaced by it and nail sinks. ... Secondly, the ship is hollow and the empty space contains air which makes the average density of the ship less than that of water and hence it floats on water.
A ship is made up of iron and steel, but it has a lot of space filled with air. This causes the ship to displace water with a weight equal to the weight of the ship. On the other hand, the needle displaces more water than its weight and hence it sinks.
