Question:
We all know that water can float on water..for example ice on water. But what other substance can float on its own kind?


Replies:
CamMee,

Any substance whose density when frozen is less than the density of its liquid form will float on its liquid. Use a science reference book to check the densities of the solid and liquid forms of the same substance and you will find an answer to your question.

e All though not too common there are a number of examples of substances whose solid phase is less dense than the liquid phase at the melting point. The element gallium (Ga) is one such case. The density of solid Ga at its m.p. is 5.9 gm/cm^3 and the liquid at the melting point is 6.1 gm/cm^3.
