Well condensed phases, solid, and liquids, have more or less constant density...

Explanation:

...whereas a GAS will uniformly fill whatever volume is available to it.

There is a marginal volume change when water melts...

And unusually liquid water is MARGINALLY MORE dense than ICE...and this is why ice-bergs float.

There is a MASSIVE volume change when water boils...
