The 115 with 100% is close but how the hell do you get 105% humidity?

"super-saturated solution". Really.


In other words, it's raining.

*WRONG*. If it _is_ raining, the humidity is somewhat -less- than 100%

There is more moisture than the 100% that the
air can support and so it falls.

Hope this helps,

A super-saturated solution is one of those strange "special cases", where
'common sense' is *not* accurate.

A simple description is that it _is_ holding more than it theoretically _can_,
contradictory as that sounds.

It comes about when you have a near-saturation condition, and the temperature
drops significantly.

*USUALLY*, when the concentration hits 100%, the 'excess' will start to pre-
cipitate out as the temperature continues to fall.

In rare instances, however, the precipitation does _not_ start as you reach,
*and*cross*, the 100% level.

This is, obviously, a "highly unstable", situation. Any sort of 'disturbance',
and the _entire_ "excess' will 'fall out', essentially 'in an instant'.


There's a fairly standard college physics experiment, where you make a pan-ful
of a near-saturated solution, using _warm_ water, and place it in a freezer.
You then run the temperaturd down, _below_ the freezing point of a saturated
(cold water) solution. The super-saturated solution does *not* freeze solid.
Then you reach in, and touch the pan. "Clunk" -- a whole sh*tload of stuff
precipitates out of solution, and the entire pan freezes solid. *INSTANTLY*.
_AND_ the pan gets too hot to touch.

The assignment is to list all the energy reactions involved. Essentially
explain "exactly what happened, in what sequence, and _why_".
