The question could also have been asked "Why can't a liquid be vaporized by rareification above the critical temperature?", and then this answer would be "beyond critical temperature the internal kinetic energy can never overcome the cohesive forces". This gives us a contradiction without casting any light on the physics. The difficult, but important truth is that there is no essential difference between liquids and vapors unless you can restrict your considerations to a region of phase space that doesn't included paths around the critical point. | |

Of course, these are all suggestions. Feel free to answer in your own way; I'm just pointing out that the answer, as it is, won't be viewed as contributing much of anything to this subject | |
