Question

State two characteristics of matter demonstrated by: a)diffusion b)Brownian motion


Please help me ..............

Answer 1

Diffusion:

Diffusion is nothing but the movement of molecules from it's higher concentration to lower concentration.

Or

The spreading out and mixing of a one substance into another substance due to the motion of its particles is called diffusion.

Brownian motion :

The zig-zag movement of small particles suspended in a liquid or a gas is called Brownian motion.Brownian motion tells us that the particles are tiny nature and the particles of a matter are constantly moving.

Answer 2

Diffusion
Intermixing of particle of two different type of matter is called diffusion

Brownian motion
Colloidal particles are in the state of rapid zig-zag motion called brownian motion
