Why can we smell food when it is being cooked?

The molecules produced by these cooking reactions are called volatiles, meaning that they evaporate easily, which allows them to reach your nose and mouth so you smell them (and spread through the whole house). … The particles can then diffuse through your house faster and then everything smells delicious.

When food cooks you can smell it because?

Diffusion . The molecules causing the scent will spread out through the air. If the air near the food can circulate towards you, then that air can carry the molecules that cause the scent. If the concentration of molecules is high enough when it reaches you, then you can smell the food.

Why can you smell food that is cooking in the kitchen when you are in a different part of the house?

There is a phenomenon called Diffusion. In diffusion, molecules of solid, liquid or gas spread from the region of their higher concentration to the region of their lower concentration. … By diffusion, the smell spreads to the whole room and thereby whole house, so anyone standing at a distance, Can smell it.

How do smells travel through the air?

A smell is created when a substance releases molecules (particles) into the air. … Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.
