Diffusion

Diffusion

1. as the particles of liquid and gas are constantly moving the particles can mix and spread without being stirred

   • this process is called diffusion

2. brownian motion - the constant random movement of tiny particles caused by collision with air or water molecules, which are themselves in continuous and random motion

3. ammonia and hydrochloric acid particles move under brownian motion as they hit air particles in the tube - when they meet white fumes ( ammonium chloride) form
