colloid
- Adjective. Glue-like.
- Noun. (chemistry) A stable system of two phases, one of which is dispersed in the other in the form of very small droplets or particles.
- Noun. (meteorology) An intimate mixture of two substances one of which, called the dispersed phase (or '''colloid'''), is uniformly distributed in a finely divided state throughout the second substance, called the dispersion medium (or dispersing medium). The dispersion medium may be a gas, a liquid, or a solid, and the dispersed phase may also be any of these, with the exception that one does not speak of a colloidal system of one gas in another. A system of liquid or solid particles colloidally dispersed in a gas is called an aerosol. A system of solid substances or water-insoluble liquids colloidally dispersed in liquid water is called a hydrosol.
