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.

  1. a

    State the behavior of particles in a suspension.

    Aim for approximately 1 distinct marking point.
