Diffusion
If someone is cooking in the kitchen it doesn't take long for the smell to travel around the house to other rooms. This is because of diffusion.
Diffusion in gases
When chemicals, like the smell of perfume or burning toast, are let loose in a room, the particles mix with the air particles. The particles of smelly gas are free to move quickly in all directions. They eventually spread through the whole room. This is called diffusion.
You don't have to mix the gases by waving your arms around - it mixes on its own. Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases
Hope it helps u if yes pls check in brilliant list
