Flour in water forms a suspension

In chemistry, a suspension is a mixture of two or more substances. In a suspension, very small pieces of solid are spread through a liquid but do not dissolve. [1] If left still, the solid pieces will separate from the liquid and either fall to the bottom or rise to the top. Sand in water is a suspension. Suspensions may separate quickly or stay suspended for a long time, depending on what they contain.

If a liquid is suspended in another liquid, it is called an emulsion. Milk is an emulsion. If a liquid is suspended in a gas it is an aerosol. Mist is an aerosol.
