Water is a polar molecule which means that it has both positive and negatively charged ends. Like the poles of a magnet the poles of a water molecule are attracted to each other. These polar attractions are called hydrogen bonds. In its liquid state water molecules form and break hydrogen bonds at breakneck speeds. It is the coupling and uncoupling of molecules that allows liquid water to both stick together and flow.
As the energy economy of water moves toward recession (the
molecules get colder) the molecules become increasingly thrifty with their
motion. Just as a frugal investor might favor
stable government issued bonds to avoid the risks of a down market, water
molecules hedge their more fluid hydrogen bonds for steady hydrogen bonds entropicly
issued by their crystalline structure.
So what does this have to do with the rink? The rink
survived because of one of waters properties that comes partnered with its
polarity, specifically, its specific heat. Specific heat is the amount of
energy a substance can absorb before changing its temperature and water has one
of the highest specific heat values of any substance and its resistance to
changing temperature is even greater when frozen.
In anthropomorphic terms Ice is more willing to organize
itself into a solid than it is to regain the increased freedom its molecules would
enjoy as a liquid. In a down energy
economy the frozen water molecules are hesitant to liquidate their assets.
And so the rink survives due to the miracle that is water.
There was also a nice mini miracle in the form of a late New
Years Eve rain/snow storm followed by a two day respite from the tropical
winter. January started with temperatures in the teens and the accumulated snow
made for nice patch material to fill the accumulated holes in the rink. Over those two days I carefully but aggressively
flooded the rink and gained several centimeters of ice.
The temporary relief from rising temperatures (we were back in the fourties again today) along with my renewed
confidence in the forgiving properties of my favorite polar molecule was what I
was waiting for and has helped me enjoy a happy new year.
I feel ya, and I was raised to "think snow," and I am dedicated to a white christmas as much as anyone alive but..
ReplyDeletei have to be grateful for the comfort and safety the snowless winter has given to my loved ones who aren't walking easily this year.
So am counting my blessings, and happy to still be waiting for big snow.
