Answer:

If the density of the material is greater than the density of water, the object will sink, regardless of how large or small it is.

Explanation:

This is a slightly tricky one.

The metal sinks because its density is greater than the density of the water. This remains true if the size of the piece is smaller.

For a very tiny piece, though, surface tension can cause the object to remain at the top of the water. For example, it is possible 'float' a steel needle on water, using the surface tension, even though steel is more dense than water.

In general, though, if the density is greater than the density of water, the object will sink, regardless of how large or small it is.
