Does Water Float Or Sink?

Recommended Posts

It sinks in oil and floats in Mercury. In pure freshwater, pure freshwater is still. Don't try and get philosophical with us, we iz rational cunce.

surely it floats, otherwise water at the top would be constantly sinking down to the bottom and create a continuous whirlpool

Will is correct. What's important to know is the density of the two objects/fluids/things: the density of water and the density of whatever the water is "in". We commonly think of everything floating or sinking in water. We compare the density of things with respect to water mostly because on Earth, water is everywhere and we're more likely to come into contact with it than another fluid (at least one in which we can easily do a float/sink test with).

 

Go to somewhere like one of the Jovian planets and your ocean of water is just methane or some other flavor of gas, so an alien living there would have a different perspective than ours, in terms of the "universal" benchmark for determining what sinks or floats.

but by the same logic wouldn't the water at the bottom be constantly floating to the top?

By his logic, water would just be spewing upwards forever (because there was no "medium" specified in which water is sinking/floating to).

 

You guys should read up on the spinning bucket problem if this kind of discussion interests you: http://en.wikipedia.org/wiki/Bucket_argument

oof. good point sir.

 

edit - i think the water being pushed to the top wouldn't be floating up though, it would be being forced up by the other sinking water

 

double edit - but then again you could reverse the whole thing and say it's floating, not sinking
