A colloid has particles small enough that they will never settle out; brownian motionkeeps them in suspension. A colloid shows the Tyndall effect.
An emulsion or suspension has droplets or particles which, due to their larger size, separate from a suspension.to form a layer or precipitate.

Describe the differences between colliods and suspensions?
Colloids do not settle out; suspensions eventually do settle out. Particles in colloids are smaller than particles in suspensions.
What happens to the particles at absolute zero?
The particles freeze.
What happens to energy particles when they are frozen?
the particles move slow
What are the three types of colloidal system?
The 3 types of colloidal system are: 1. Lyophilic colloids 2. Lyophobic colloids 3. Association colloids
What are the harmful and beneficial effects of colloids and solutions?
some colloids cause pollution in the environment...some colloids release cfc's that contributes to the ozone layer depletion...
Why paints are colloids?
the solid particles in these colloids are mixed with the particles of a liquid. the dispersed particles do not dissolve into the liquid therefore the particles do not settle.
What mixture has the smallest particles?
COLLOIDS
Describe the differences between colliods and suspensions?
Colloids do not settle out; suspensions eventually do settle out. Particles in colloids are smaller than particles in suspensions.
How do particles in solutions differ from those in suspension?
The dispersed particles of a suspension are larger than the particles of a colloid.
Are colloids homogenous?
Colloids are very small particles of a substance suspended in a mixture making them homogeneous.
A mixture where the particles are dispersed but settle out?
They are called colloids.
How can collids be distunguished from suspensions?
Particles cannot be filtered from colloids
Mixture whose particles are not heavy?
You think probable to colloids.
A mixture can be classified as a solution suspension or colloid based on .?
Colloids are classified frequently as solutions because the particles have very small dimensions.
Why do colloids produce the Tyndall effect?
The partiales of a Suspension are Big. Therefore they Show tyndall effect
What is the mixture in which dispersed particles are too light to settle out?
They are called colloids.
Mixture whose particles are not heavy enough to settle out?
They are called colloids.
