What is a sol to a gas?

A sol is a type of colloid where solid particles are dispersed in a liquid medium, forming a stable mixture. In contrast, a gas is a state of matter composed of particles that are far apart and move freely, filling the volume of their container. While a sol consists of solid particles suspended in a liquid, gases do not have a solid component; instead, they are characterized by their ability to expand and occupy space. Thus, a sol is fundamentally different from a gas in terms of composition and physical behavior.
