Re: Can running, (moving) water be below freezing.

Dear Sonny,

Yes, water can still move and remain liquid even when it is colder than 32 
degrees Fahrenheit.  In the case of a flowing stream at 30 degrees F, it is 
the movement of the water that actually keeps it from freezing.  As water 
cools, the water molecules begin to pack together more tightly and begin to 
'stick' together to form very small ice crystals.  But, if these molecules 
are  flowing in a stream, the molecules of water are bounced and jostled 
around.  This keeps the molecules from sticking together and forming ice.   
 
Best of luck and thanks for your question, Sonny!

Cheers, 
Diane
