Upon leaving the house early one frosty morning, I noticed the emblem on my car was frosted over on all the letters but one. The N was completely frost-free (see Photo). The outside temperature was hovering around 0 掳C. If all the letters were constructed of the same material, surely they would all appear the same, so why is the N special?
