Title: Floating a liquid on a gas
Post by: Eudoxus on August 15, 2011, 09:40:35 PM

So I know there are very dense gases out there. And there are very light liquids. Is it possible to have a liquid with a lower density than a gas, float on top of the gas?

The densest gas I know of is sulfur hexafluoride. Are there any liquids out there light enough they could "float" on SF₆? And that won't dissolve the SF₆?
