Examples of sublimation:
The process of solid iodine directly changing into iodine vapor by heating is sublimation.
The gradual shrinking of mothballs is sublimation.
When ice is heated, it turns directly into steam, which is sublimation.
The bulb will turn black after a long time because the filament (tungsten) is sublimated by heat and the gas condenses when it touches the glass.
It is sublimation that dry ice becomes gaseous carbon dioxide when heated.
The fog seen on the stage is a small water droplet that absorbs heat by sublimation of dry ice and is liquefied by water vapor in the air when it is cold, which reduces the surrounding temperature.
