Answer:
The particles dispersed in a colloid are much smaller than those in a suspension and do not settle out.
Step-by-step explanation:
A suspension is a heterogeneous mixture of substances that does settle out on standing. The particles in a suspension are large enough that they can even be seen with naked eyes. The particles in a suspension are more than 1,000 nm in size.
A colloid contains particles that are lesser in size than a suspension (about 1-1,000 nm). The particles in a colloid can not be seen except with the help of a light microscope.
