Describe the process of sublimation and its applications.
Sublimation is the transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase .
Here are several application of sublimation :1.Dry ice sublimes while keeping its area cold. No water is produced to wet things.2.Naphthalene, mothballs, sublime into the air, not getting the area wet, while keeping moths away.3.Iodine can be displaced in a compound and collected on the bottom of a watch glass with ice on top, in deposition, opposite of sublimation. This also occurs as frost is formed on a window from humid air as the dew point falls below freezing.
