Detailed Solution

The above statement is True.
A submarine of iron and steel floats in water, whereas a small piece of iron sinks in it. A submarine is not a solid block of iron and steel throughout. Instead, a submarine is a hollow structure of iron and steel, which contains a lot of air. Air has a very low density. Due to the presence of a lot of air in it, the average density of the submarine becomes less than the density of water. Therefore, a submarine floats, but solid iron pieces sink into the water.
