Question

The Aroma of delicious food spread across the room by which property and why

Answer 1

hi there

the answer is diffusion

by diffusion we mean random movement of particles from higher concentration to lower concentration

the air paticles around the food have a high concentration through diffusion that decreases its concentration but spreads it out.

Answer 2

When molecules are spread out evenly, diffusion seems to stop. Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. ... Since our brains are used to the smell of air, we don't smell the oxygen, nitrogen, or carbon dioxide.
