Flour in water forms a suspension

In chemistry, a suspension is a mixture of two or more component. 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 an example of 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.
