Sublimation. You see it on a cold sunny day when ice is bonded to pavement and over time it evaporates.

Yes! The process is called sublimation, and it can happen at certain combinations of temperature and pressure. [This chart](https://upload.wikimedia.org/wikipedia/commons/thumb/3/33/Phase_diagram_of_water_simplified.svg/800px-Phase_diagram_of_water_simplified.svg.png) shows what state water is in at various combinations.
