In cooked food, the particles of matter absorb heat and turn into gaseous state and mix with atmospheric air. So the smell of food reaches our nostrils without our entering the kitchen through air.
Why the smell of food reaches your nose?
It is because of a phenomena called “diffusion”. … The particles of these gases move very quickly and mix up with air by diffusion. When the air containing these gases reaches your nose, you get the smell of food being cooked in the kitchen(even without entering the kitchen).
How does smell of cooked food spread so fast?
The smell of food being cooked spreads very fast because of the kinetic energy produced. whenever there is an increase in temperature the kinetic energy also increases causing the particles of matter to move fastly by the process of diffusion.
How the smell of cooking food spread over the entire room?
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.
Can you smell the aroma of food cooked in the kitchen even when in the living room?
Answer. 1. Yes, the smell spreads to the whole room and thereby the whole house, so anyone standing at a distance Can smell it.
Why do the smell of hot sizzling food reaches you?
The smell of hot sizzling food reaches to you several meters away but to take smell from cold food you have to go close because particles of hot sizzling food possess large kinetic energy and diffuse in air rapidly and reach several meters away whereas particles of cold food possess less kinetic energy and are not able …
Why the smell of hot cooked food reaches us in seconds?
Ans: At higher temperatures the particles of gas moves faster as the kinetic energy increases with increase in temperature . So the smell (vapour particles) of hot cooked food reach several meters within seconds.
Why can we smell hot food from a distance but not cold food?
When we increase temperature, the particles move with more speed and gain kinetic energy. Hot food has a very high temperature. … So we can say that we smell hot food from a distance because of diffusion.
Why we can smell food from a distance?
We smell hot food from distance because of diffusion process. … As hot food has more temperature , the particles gain Kinetic energy and move with greater speed. Hence it spreads a greater DISTANCE.
How does smell travel through 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. … Some people have no sense of smell, or they lose it during their lifetime.
Why can you smell food cooking?
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).
How do we able to smell dishes being prepared in kitchen?
Solution. 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.
When your mother cook food you can smell the food across the House Why?
Answer. When your mom cooks food the food is hot and when food is hot, the smell gets transported easily in air. As air is present all over your house, the smell spreads.
How fast does smell travel through the air?
f we assume that the average mass of air (since it is a mixture of different gases) is 28.9 g/mol (or each gas particle is around 4.799*10 -26), and room- temperature is 27C or 300K, we find that the average velocity of a single air particle is around 500 m/s or 1100 miles per hour!
Why is aroma important in food?
Aromas play a central role in our perception of food. … That fact is why food scientists use chemical aromatics, essential oils, and botanical extracts to enhance the flavor of food and beverages. Many people, however, after initially tasting these foods, avoid them because they dislike their odd or bland taste.
