Although they are randomly arranged, they are still tightly packed, giving liquids high densities. ... This means that liquid aluminium floats on top ofsolid aluminium. Water is different from most substances: it is less dense as a solid than as a liquid, because its particles move apart slightly on freezing.

The increase in the volume of the object decreases the density so that the density of the bowl is less than the density of water so the bowl floats.
The temperature of a substance affects its density. When a substance like a solid or a liquid is heated, its molecules move faster and get slightly fur ther apart.
