Essential Chemistry for IGCSE - Particles And Purification (Section 1 - No. 25)
What observation provides evidence for the kinetic particle model and Brownian motion?
The change of state from solid to gas.
The diffusion of a gas into a vacuum.
The random movement of pollen grains in water.
The condensation of water vapor.
Explanation
Brownian motion, where particles display erratic movements in fluids, strongly supports the kinetic particle model.
