Question

Which characteristic property of particles of matter is illustrated by the phenomenon of diffusion ?

Answer 1

Diffusion: Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. One of the main characteristics of diffusion is the movement of molecules along the concentration gradient.

Characteristics of matter that are demonstrated by diffusion are:

• Particles have inter-particle spaces between them.
• Particles of matter attract each other which is strongest in the case of solid, a little less in the case of liquid, and least in the case of gases.
• The particles are moving or they are in motion.
