Question

why does an iron nail sink but not an iron ship???

Bapan Pathak · Accepted Answer

Hello,
Whether a body will float or sink depends on the density of
the body Density of a body is the mass divided by the volume of the
body
Density of an iron pin is more than water so it sinks The
density of a ship is mass of the ship divided by the volume of the
ship Although the ship is made of iron, the volume of the ship is
so huge that the density becomes less than the density of water The
reason being, ship is not a mass of solid iron There is lots of
empty spaces and other less dense substances within the volume of
the ship
Hope this helps,
