Explain qualitatively how the extent of Brownian motion is affected by the (a) size of the Brownian particle, (b) density of the medium, (c) temperature of the medium, (d) viscosity of the medium?        

Answer:

                The effect of the various factors on the Brownian motion is as follows:                

Factors		Effects
(a)	Decrease in the size of the Brownian particle.	Increase of Brownian motion.
(b)	Decrease in the density of the medium.	Increase of Brownian motion.
(c)	Increase in temperature of the medium.	Increase of Brownian motion.
(d)	Increase in viscosity of the medium.	Decrease of Brownian motion.
