Friday Science: Dew

about ten years ago, I was in need of a way to "dry" some air before using it.  I needed to remove the moisture from the incoming air.  I looked up some charts and graphs and made some startling conclusions.

If you take a fixed volume of air at any temperature and quickly lower that temperature ten degrees F, most of the "water" moisture will fall out of the air like dew on your car in the morning.  It does not matter if the air is at 200 degrees and you cool it to 190 degrees or if the air is at 60 degrees and you cool it to 50 degrees.  Relatively speaking, "warm" air can hold more water than "cooler" air.  In a very basic explanation, when cold air collides with warm air, it rains!

Lets diverge and extrapolate. 

Women can be the hottest things on the planet, with scorching fire that can leave burns that scare.  They can also purify your soul with that fire.  As expected, they can quickly "cool off" to the point of  Antarctica in August.  There must be some kind of "dew" or precipitation that falls with the temperature.  

Now, when the Alberta Clipper is released from the "Do whatever you want" answer to your weekend with the boys statement, quickly grab your remote thermosensor and locate the incoming cold spell.  A humidigraph can also be used to identify the "frost zone" front.  That is the point where it is perfectly clear and bone dry that you are going to pay dearly for even thinking what she thinks you are thinking.  Most likely you can feel you hot crossed buns drying out way before the event horizon. 

Instantly, you will see her come out the the next room wearing grandma underwear, flannel bottoms and socks.  She will spin elegantly on the crackling imported Venetian floor tile, amble to the bookshelf and starts to reading "Dancing Naked on the Edge of Darwin" before the bedroom door slams shut.  There is no need for her to lock it, the mechanism has frozen solid from the passing gale and touching it would be like licking the northern most pole.  Cold spells are always followed by a warming trends you just have to be ready to identify the dry air so you do not get burned.
