Question

Why do some iron objects such as ships float when placed in water while other iron objects such as nails sink? 1. iron ships have large air pockets inside them, making them less dense than water and thus able to float. 2. the same reason that makes planes fly in the sky?

Answer 1

Iron ships have large air pockets inside them making them less dense than water and thus able to float. Iron objects does not have any air pockets to make them light . If you ever heard that ships sink its because  the ship must  have  a hole in the air pocket and (air pockets are at the bottom layer of ships) water fills through the air pocket and adds weight making it sink.


Hope this helps :)  

Answer 2

Iron ships have large air pockets inside them, making them less dense than water and thus able to float.

What is floating?

Floating is the ability of a substance to stay above another substance due to it being less dense that that substance

Iron is denser than water, therefore objects made of iron normally sink in water.

However, air is less dense than water, so substances containing air usually float on water.

Therefore, iron objects such and ships can float on water because iron ships have large air pockets inside them, making them less dense than water and thus able to float.
