leaving the rest of the room so cold that you are frozen to an icicle. Based on thermodynamics, why is this impossible?

  1. yeah, what he said. :]


  2. thermodynamics will not allow heat energy to flow of its own accord from a lower temperature region to a higher temperature region but only from higher to lower.  This is fundamental to the meaning of temperature.  Therefore as soon as the smallest concentration of heat in the corner of the room occurred, it would be corrected by a heat flow from the corner back into the room.

  3. This would mean a spontaneous and enormous drop in entropy. According to thermodynamics, systems will always try to increase their entropy under spontaneous conditions, so this will not occur.
