How the smell of food being cooked in the kitchen does reaches us even from a considerable distance?

The smell of food cooked in the kitchen reaches us even from a considerable distance because the tiny particles of the vapour of food mix with the air and move continuously in all directions by the process of diffusion.

How does the smell of cooked food reaches us?

The smell of hot cooked food reaches us in seconds. This is due to high speed of particles (kinetic energy) of gases and large space between them shows the property of diffusing very fast into other gases. … Due to this random movement, the particles hit each other and also the walls of the container.

Why does the smell of good food diffuse from a container to your nose?

Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. … These tiny molecules of bread travel through the air throughout the house to our noses.

How does this smell reach us?

For us to detect the smell, those molecules need to enter our nose. … Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions.

Why do the smell of hot sizzling food reaches you several Metres away but to get the smell from cold food you have to go close?

Particles of cold food possess less kinetic energy and are not able to reach several meters away. … At higher temperatures, particles have high kinetic energy and move faster hence, due to this smell of hot sizzling food reaches you several meters away, but to get the smell from cold food you have to go close.

When a bottle of perfume was opened in a room?
