Question

Explain why an iron needle sinks in water, but a ship made of iron floats on water? Please do answer!!

Answer 1

As the density of an iron nail is more than that of water, the nail sinks in water.

• The volume of water displaced is much greater than the volume of the iron ship.

Hence, according to Archimedes' principle, the upthrust is more than the weight of the ship.

• That is why the iron ship floats in water.

Answer 2

Answer:

1 Answer. The average density of iron needle is greater than water, therefore, it sinks.
