I believe it is called "sublimination"
this link has a great, um, graphmobob illustrationization. I mean "phase diagram"

Sublimation does not involve changing a liquid to a gas. Sublimation is the phase transition of a substance directly from a solid to a gas without passing through the liquid phase.
Sublimation is a phase change that does not involve changing a liquid into a gas. Sublimation occurs when a solid directly turns into a gas without passing through the liquid phase.
Sublimation is the process when a solid changes directly into a gas without first becoming a liquid. This occurs when the conditions are such that the solid phase can bypass the liquid phase and enter the gas phase.
The energy required to create a phase change without changing the temperature is known as latent heat. This energy is needed to break the intermolecular forces holding the molecules in a particular phase, such as solid to liquid or liquid to gas, without increasing the temperature of the substance.
This change of phase is called freezing.
Sublimation is the phase change that changes a solid directly to a gas or vapor without first changing to a liquid. In this process, the solid particles gain enough energy to break free from the solid structure and enter the gas phase without passing through the liquid phase.
The process of changing from a solid to a gas is called sublimation, where a substance directly transitions from a solid phase to a gaseous phase without passing through the liquid phase. The reverse process, changing from gas to solid, is called deposition, where a substance transitions directly from a gas phase to a solid phase.
This type of phase change is called evaporation.
Sublimation is the phase change from solid to gas without passing through the liquid phase. In sublimation, the solid directly changes into a gas without becoming a liquid first. Examples include dry ice (solid carbon dioxide) turning into carbon dioxide gas and camphor crystals turning into vapors.
Solid to liquid.
The process of changing a gas directly to a solid is called deposition. This involves the gas molecules losing energy and transitioning from a gaseous state to a solid state without passing through the liquid phase.
This phenomenon is called melting, the ordered molecules of the solid becomes non-ordered in the liquid phase.
