Random movement of dust particles-When dust particles colloids with air. It move srandomly. so this random motion explains the colision in molecular motion of gas present in air and it shows that gas particles are in constant random motion.
Diffusion of Ammonia and HCl gas-
We soak mcotton in ammonia and HCl and place at two different ends. For each cotton wool, chemicals evaopurate. These vapours move in random motion in air. Ammonia moves faster than HCl because it has lower mass.
