10 Examples of Gas to Solid (and vice versa)

When an element goes from a solid state to a gaseous state it has the name of direct sublimation . However, if the process is inverse (passing from the matter of gaseous to solid) the process is called crystallization or regressive or inverse sublimation .

These phenomena may be due to objects (matter) being exposed to large (usually abrupt) changes in temperature and pressure.

However, most elements go from a gaseous state to a liquid   ( condensation ) and from there to another solid state. This is because the molecules of that element contract when they pass from the gaseous state to the liquid and from there to the solid, so the change from gaseous to solid must take place under specific conditions.

The same happens when the material has to change from solid to gas.



Examples of solid to gaseous (sublimation)

  1. Sulfur (when heated it will turn directly into gas)
  2. Solid iodine (the same as in the previous example)
  3. Incense
  4. Wood (when it burns much of it turns into smoke)
  5. Naphthalene
  6. Dry ice
  7. Carbon dioxide
  8. Acetic acid
  9. Benzoic acid
  10. Arsenic

Examples of gaseous to solid (reverse or reverse sublimation)

  1. Frost formation
  2. When iodine crystals are formed on the basis of iodine in the gaseous state.
  3. Snow formation
  4. The formation of new planets that are composed of particles in the gaseous state (supernovas).
  5. Vaporized metals that solidify on crystalline surfaces
  6. Sulfur
