Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Suspension (chemistry)?Approximately 1 µm to 1 mm
2. What is the classification?Heterogeneous mixture
3. What is the stability?Inherently unstable; particles settle over time due to gravity
4. What is a suspension in chemistry?A suspension is a mixture where solid particles are big enough to be seen and they float in a liquid but will eventually fall to the bottom.
5. Why do the particles in a suspension settle down over time?The particles settle because gravity pulls them down faster than the liquid can keep them up.

Sedimentation: The process where suspended particles settle out of a liquid due to gravity.
Brownian Motion: The random movement of particles suspended in a fluid (liquid or gas).
Viscosity: A measure of a fluid's resistance to flow.
Heterogeneous Mixture: A mixture whose components are not uniformly distributed throughout.
