Question

What does the diffusion of gases tell us about their particles?

Answer 1

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

Diffusion in gases is faster than in liquids & solids because in gases the particles are not fixed they can vibrate in all directions and move freely.

Hence diffusion of gases tells that the particles of a gas have  higher movements unlike in solids &liquids.

Answer 2

difussion of gases tell that the particle of gas move randomly at high speed
