What is crystallization?

Feb 6, 2016

When a substances in the gaseous phase experiences a drop in temperature such that the particles move slower and closer together and it converts directly into the solid phase.

A good example of a chemical which readily undergoes sublimation and crystallization is carbon dioxide. ($C {O}_{2}$).

Sublimation : $C {O}_{2 \left(s\right)} \to C {O}_{2 \left(g\right)}$.

Crystallization : $C {O}_{2 \left(g\right)} \to C {O}_{2 \left(s\right)}$
