Question

A piece of iron sinks in water but large ships made of iron floats on water?

Answer 1

a piece of iron sinks . Because its mass - volume ratio is not enough inorder to floats. But a ship can float even though it is made of iron, cause mass by volume ration is enough to make them sink.In a ship there are large amounts of free space inside. This will provide large amount of volume. This will make them float
