Question

How does the smell spreads when food is being cooked in the kitchen . Explain this in terms of molecules

Answer 1

Answer :


When the food is being cooked in the kitchen, we observe that its smell spread all around, there is a process behind this phenomenon

That is DIFFUSION


DIFFUSION -- The movement of molecules present in the air from the higher concentration towards the lower concentration.

So, when the food is being cooked then the molecules present in the air near the food start spreading towards the area of lower concentration means where there is no food smell.

So basically this makes the food's smell to spread all over.


There is also a fact we all observe that the smell of hot cooked food spread faster than that of the cold food.

Diffusion is responsible behind this

Because the molecules of hot food consist more kinetic energy (as they are hot) so this makes them to move fastly where the molecules of cold food consist less kinetic energy which makes the molecules move slowly.

Therefore, behind the spreading of food's smell, the phenomenon responsible is Diffusion.

Answer 2

Answer:

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. This process is called diffusion.
