(a) What is Brownian motion? Draw a diagram to show the movement of a particle (like a pollen grain during Brownian motion.)
(b) In a beam of sunlight entering a room, we can sometimes see dust particles moving in a haphazard way in the air. Why do these dust particles move?
Answers
Irregular Travel is Brownian Motion
Explanation:
(a) The crisscross or irregular way made by the particles of body is called Brownian movement.
(b) The continuous crisscross development of small residue particles suspended in air results from their impact by the quick moving particles of air. This aimless or irregular bit of particles is known as Brownian movement.
*Refer the Diagram
Explanation:
(a) Brownian motion is called the zigzag movement of the little particles suspended in a liquid or gas.
The diagram to show the movement of a particle is attached in the attachment below
(b) Suspended dust particles can be seen traveling haphazardly when a ray of sun light enters a room. This is due to the rapidly traveling particles of air continuously strike the dust particles and because of this continue suspended with the gravity act on them. This is one Brownian motion example.
