We consider boiling and freezing
as inverses, effects that occur at very different temperatures. Nonetheless,
under situations of low air pressure these two can arise together, as we see in
this spectacular video.
Materials can only be liquid
in the attendance of a gas to put on vapor pressure. If there is no pressure, a
substance will go straightforward from solid to gaseous stage as it warms. If
you do this in a bounded space the gas formed will build up, generating
pressure as it does so, until a liquid stage is possible. If not surrounded,
the gas will leak and the procedure can last indefinitely.
The most aware example is
solid carbon dioxide, also recognized as dry ice. Liquid carbon dioxide desires
much higher pressure than most other normal substances. Take some hard carbon
dioxide into a room and watch it converting directly to gas.
The video above is exactly
what occurs if a liquid is positioned in conditions where the temperature is
right at the point where it freezes and the gas pressure is detached. Some exposure
has incorrectly described the video as presenting the triple point.
