When a solid turns into a gas, this is called sublimation. When a solid is actually in the gas, there is no scientific name.
The commonly known 4 stages of matter in order from coldest to hottest are "solid," "liquid," "gas," and "plasma." However, some scientists now believe that there is a 5th stage which is at cooler temperatures than the "solid" stage. This stage is, at present, refered to as "atom stuff" --a funny name for a supercooled metal, considering the work the went through to get it that way, i know, but that's what they call it. Sooner or later, it is still possible that they will change this name to something cooler.
Deposition. The reverse process (going from a solid directly to a gas) is called sublimation.
Evaporation. If it changed directly from a solid to a gas, with no liquid stage, THAT would be sublimation.
The phase of solid to gas is called sublimation.
Sublimation is the transition directly from solid to gas, without the intermediary liquid stage. The reverse (the transition directly from gas to solid) is called deposition or desublimation.
The process of changing a solid directly to a gas skipping the liquid stage is called sublimation.

Which gas? There are lots of them. Gas is a stage of matter (solid, liquid, gas) not what you seem to think it is. So your answer is - who knows.
Deposition. The reverse process (going from a solid directly to a gas) is called sublimation.
Evaporation. If it changed directly from a solid to a gas, with no liquid stage, THAT would be sublimation.
Melting is solid to liquid. Sublimation is a change from solid to gas with no liquid stage. Dry ice (solid carbon dioxide) sublimates directly to carbon dioxide gas. No liquid- hence "dry" ice.
