Why does iodine,
(s) , spontaneously sublime at room temperature?
A) The contact of iodine,
(s) , with the water vapor in the air causes the sublimation process.
B) Iodine,
(s) , pulls
from the air as it self-oxidizes under sublimation to
(g) .
C) There is an increase in entropy as solid iodine,
(s) , sublimes into iodine vapor,
(g) , because in the gaseous phase energy is more readily dispersed.

(s) subliming to
(g) is highly exothermic and therefore proceeds spontaneously.
