Leading back to first-year chemistry ...
http://en.wikipedia.org/wiki/Arrhenius_equation
where the rate of a reaction doubles every 10C.

A variation on the universal equation:

 Something = Something Else * e ^ -(Energy of the thing / k * T)

Where k is Boltzman's constant and T is temperature
relative to absolute zero.
