Answer 1

Hey!

___________________

a) Diffusion - Movement of molecules from a region of high concentration to region of low concentration or mixing of two substances.


• Particles of matter are always in motion. That's why, it can diffuse with something else.

• Particles have spaces between them.

b) Brownian movement - Zig-zag movement of particles suspended in a liquid.

• Particles of matter are very small.
