Question

Why a metal rod sinks but ship made of same metal doesnt sink in water?

Answer 1

Hope this works.

This is according to my concept.

Answer 2

metal rod is denser than water

ship is not a solid block of iron and steel.

a ship is hollow object made up of iron and steel which contains lot of air in it

due to prsence of a lot of air in it the average density of ship becomes less than the density of water

since the average density ship is less than water it floats on water

when ship is placed in water it sinks to a certain level so that the weight of water is displaced by its submerged portion is equal to weight of the ship

since the ship fulfils the condition of flotation it floats on water
