what are some examples of colloids?
like a mixture,compound or sometin....
im looking for something like a colloid is water and oil mixed together and so on.
thx :)
A colloid is a mixture in which finely divided particles are dispersed within a continuous medium so that the mixture can not be filtered easily or settled rapidly.
A water/oil mixture (milk) is an example of a liquid in liquid colloid. An example of a gas in liquid colloid is a whipped egg white.
There are some further examples here:

which also shows how colloids are classified further.
ummmmmmmmm......... i acctually havve a question what particales are in a colloid?????? help!!!!!!!
Colloids are heterogeneous mixtures where particles of one substance are dispersed evenly throughout another substance. Here are some examples of colloids:
1. Milk: Milk is a colloid of fat particles dispersed throughout a water-based solution.
To identify a colloid, you can observe its properties. In this case, milk appears as a whitish liquid with a milky appearance. Additionally, you can perform a scatter test by shining light through the milk. The light will scatter due to the dispersed fat particles.
2. Fog: Fog is a colloid of tiny water droplets suspended in the air.
To identify fog as a colloid, you can observe its appearance. Fog consists of visible tiny water droplets floating in the air, forming a mist-like appearance.
3. Whipped Cream: Whipped cream is a colloid of air bubbles dispersed within a liquid fat.
To identify whipped cream as a colloid, you can observe its texture. Whipped cream appears as a fluffy, semi-solid substance due to the presence of air bubbles throughout the liquid fat.
4. Gelatin: Gelatin is a colloid of protein molecules dispersed in water.
To identify gelatin as a colloid, you can observe its consistency. Gelatin is a semi-solid substance that sets when cooled due to the dispersed protein molecules forming a network structure.
Remember, when identifying colloids, you can use visual cues such as appearance, texture, and consistency to determine whether a substance is a colloid or not.
