Sublimation is the direct phase change of a solid to a gas.

Examples are snow and ice "evaporation" on a sunny day. While the temperature may be too low for melting, followed by evaporation, the direct solar energy input to the snow or ice can cause the direct change of the solid water form to the vapor form. This is one mechanism of the water cycle.
