.......Water is the heavyist liquid on earth other than mercury......





???? I don't know if there are other qualifiers to this statement or not, but there are a bunch of liquids heavier than water.




Not to mention, "liquid" is one of 3 forms of matter that a substance can be. H2O can be a solid (ice) liquid (water) or gas (steam).

And since density changes with temperature you must add a temperature as another qualifier. I have no idea what liquid oxygen weighs per gallon, but I can tell you that it's VERY cold. And at some point, mercury will freeze into a solid just as at some point, iron turns into a liquid.
