Essential Chemistry for IGCSE - Particles And Purification (Section 7 - No. 37)
What does the Brownian motion experiments help explain?
That all matter is made of particles.
That the particles are in constant motion.
The diffusion rates.
The relationship between temperature and pressure.
Explanation
Brownian motion showed that the random movement of tiny particles provided evidence for the constant motion of particles, a key point of the kinetic particle theory.
