Give scientific reason:An iron nail sinks in water but a ship made from iron floats on water.

Answer»

1. An iron nail sinks in water because its density is more than that of water. 

2. A ship made from iron, due to the particular shape given to it, displaces a large amount of water so that the buoyant force acting on the ship due to water balances the weight of the ship. Hence, the ship floats on water.
