Q. What special qualities are given to the ship so that it can float on water?
Posted by: Neelimathegr8
A. The density of iron is more than the density of water. But still the ship does not sink because it has a large volume. So it displaces a large volume of water which provides a large upthrust. This upthrust balances the weight of the ship and helps the ship to float.
