Detailed Solution

The above statement is false.
When a substance is dropped in water, it floats or sinks with respect to its relative density. Relative density is defined as the ratio of the density of a given substance to the density of the water. The ship is relatively hollow and contains a lot of air, due to which its density is much less than the density of water. But iron pieces have a density greater than that of water. So, a substance with a relative density of less than 1 will float, and a relative density greater than 1 will sink.
The correct statement would be that a ship of iron and steel floats in water, whereas a small piece of iron sinks in it due to its relative densities.
