When substances change directly from a solid to a gas without going through a liquid state.
Sublimation
100
A stable homogeneous mixture in which very small, fine particles of one material are scattered throughout another material, blocking the passage of light without settling out.
Colloid

What's the difference between vaporization and evaporation?
Evaporation is only on the surface of the liquid. Vaporization is when the entire liquid reaches it's boiling point.
