How is sublimation from a solid to a vapor different from the boiling process?
What will be an ideal response?
In principle the sublimation process is the same as the boiling process in that a
pure substance becomes a saturated vapor and possible a superheated vapor. In
boiling saturated liquid becomes saturated vapor whereas in sublimation a
saturated solid becomes a saturated vapor.
