Kinetic Particle Theory

Description

Random Movement in Suspensions

In a suspension, tiny particles are dispersed throughout a fluid and exhibit random motion. This behavior is a key aspect of the kinetic particle theory.

Observing Suspensions

When observing a suspension, one can see that the particles do not settle immediately but exhibit random motion before eventually settling over time.

  1. a

    State what happens to the particles in a suspension over time.

    Aim for approximately 1 distinct marking point.
