It is my understanding that when ice cubes “shrink” in the freezer over time, it is due to sublimation. How does sublimation work exactly? What causes the change in state?
In: Chemistry
Sublimation is going from solid to gas without becoming a liquid. One at a time, or so, water molecules get enough energy to pop loose from the outer edge of the cube, and the fans and self-defrosting mechanism in the freezer drags them away before they can re-attach to the surface.
