drowning

Why would a person remain suspended on the surface of the water if he had already died from drowning? What about the high surface tension created by the hydrogen bonds? :shock:

Whether something floats or sinks in water has little to do with surface tension. If the mass of water displaced by the object weighs more than the object does, then that object floats--like a battleship--or a body.

Mmm, yus. Surface tension only really applies to very small things, like certain insects.
