Question

Why iron boat float is water whereas a iron pin sinks?​

Answer 1

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.

While the shape of an iron ship is made in such a way that it displaces more weight of water than its own weight.

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.

Answer 2

The main concept for this is density

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.
