Hot/Cold water

 Today I learned about density.  If water is dense then it must be cold.  Because cold water is more dense.
   So having told you that
you should know that warm water -or boiling water if you prefere- is less dense.  The more dense the water the more it sinks.  The less dense the water
the more it would expand.   Or float....... I wouldn't say float but you know what I mean.
