Charcoal briquettes are solids.
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
Ice is a solid and when melted it turns into a liquid freeze it again and it is solid
the process of passing from a solid to a liquid is liquification but the passage from liquid to solid ist solidification
Iodine and charcoal can be separated through sublimation, a process where iodine transitions directly from a solid to a gas without passing through the liquid phase. By heating the mixture, the iodine will sublimate, leaving behind the charcoal. The iodine gas can then be collected and cooled to form solid iodine crystals, effectively separating the two substances.
Solid
Carbon is usually solid by itself under the allotropic form: diamond, soot and charcoal.
Charcoal is not a colloid; it is a solid material primarily composed of carbon. A colloid is a mixture in which fine particles of one substance are dispersed in another, typically a liquid, without settling out. While charcoal can be used in certain colloidal mixtures (like activated charcoal in suspensions), the charcoal itself does not fit the definition of a colloid.

Liquid.
Solid
Crystals can form on charcoal through a process called sublimation. This occurs when a solid substance transitions directly into a gas state without passing through the liquid phase. By heating the crystalline substance on charcoal, it creates vapors that then cool and solidify back into crystals on the surface of the charcoal.

it is a gas
Charcoal.
change of a liquid to a solid
A gas is not a liquid or a solid.
