ships are made made from iron but then also they do not sink in water give a brief answer
Answers
Explanation:
t's because an iron ship is not completely solid. ... So the average density of the ship as a whole is less than the density of water. Therefore immersed portion of the ship displaces water equal to its weight. So the ship floats whereas a sheet of iron is compact and there are no air spaces inside it.

Answer:
The answer lies in the understanding of Archimedes’ Principle: a upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
To float, the needle would need to displace its own weight of water but, as the volume of a needle is very small, then so is the weight of water displaced and therefore the upthrust (or buoyant force) is insufficient to support it.
On the other hand, a ship - whilst weighing many thousands of tons - displaces a large volume (and therefore weight) of water. Hence the buoyancy force acting on the ship is much greater than the weight of the ship itself, making it to float on water.
“The density of nail (as of iron) is much larger than the water. So it sinks easily. The weight of the water displaced by the ship is equal to its weight, so it floats.Whereas the weight of the water displaced by the iron nail is less than its weight so the iron nail sinks”
Explanation:
This is a very big answer but you can mark the important points from this.
