Revise CIE IGCSE Physics 2.1.2c Brownian motion with the question bank and revision guides.
Know that the random motion of microscopic particles in a suspension is evidence for the kinetic particle model of matter • Describe and explain this motion (sometimes known as Brownian motion) in terms of random collisions between the microscopic particles in a suspension and the particles of the gas or liquid • Supplement: Know that microscopic particles may be moved by collisions with light fast-moving molecules and correctly use the terms atoms or molecules as distinct from microscopic particles
