Answer 1

$\rm\underline\bold{Answer \purple{\huge{\checkmark}}}$

1) Diffusion

2) Diffusion is the process involved in this as the fragrance quickly spreads in the entire room.

3) A light particle, such as a pollen grain, randomly moves with zigzag motion in a liquid medium. This irregular motion is induced by the motion of molecules composing the dispersion medium and is well known as Brownian motion.

4) d) Both assertion and reason are incorrect.

Explanation of 4th no.

Liquids diffuse slowly as compared to gases. Liquid molecules are less free to move because intermolecular forces in liquids are greater than in gases.

5) Blue vitriol - CuSO4

ㅤPotassium permanent - KMnO₄

ㅤNeutral salt - NaCl

ㅤCopper sulphate - CuSO4

6) Dust particles

7) Air

8) Brownian motion

9) The fast moving air molecules are constantly hitting the tiny dust particles, causing them to move rapidly in a very haphazard manner.

10) The gaseous matter 'air' is made up of tiny particles that are constantly moving.
