What is the name of the process from a gas to a solid?

Question

What is the name for the process of a gas going DIRECTLY into a solid. I need to know for science class and i can't find it anywhere! thanks!

Answer 1

Solid to liquid = melting, fusion
Liquid to gas = boiling, evaporation
Solid to gas = sublimation
Gas to solid = DEPOSITION
Gas to liquid = condensation, liquefaction
Liquid to solid = freezing, solidification

Answer 2

Depends if you need to know for a science weather class, or a chemistry class.

If you're asking a weather question, the answer is sublimation, which is also the term that both meteorologists and chemists use to describe the process of a material going directly from a solid to a gas. (dry ice does this)

But if you're talking chemistry, then the term for going directly from a gas to a solid is deposition.

More detail:

To understand the weather, you need to understand what happens when water changes its state. These changes are:

Evaporation: From liquid to gas (water vapor).
Condensation: From gas (water vapor) to liquid. (Related: Evaporation and condensation graphic)
Freezing: From liquid to solid (ice).
Melting: From solid to liquid.
Sublimation: From gas directly to solid without becoming liquid. *
Sublimation: From solid directly to gas.

*(Note: In chemistry a change from vapor to solid is called "deposition," and meteorologists in other English-speaking countries use this term for the change of water vapor directly to ice. But American meteorologists generally use "sublimation" for both the change to ice and directly back to vapor.)

Answer 3

supercondensing or supercooling
