(a) What is Brownian motion?
(b) As temperature is increased, how will the movement of smoke particles in Brownian motion change?
(c) What would you expect to see if the smoke particles were much larger? Why?

Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. ... Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
